I suspect that it is due to the campaign cinematographic intros.  As the two
campaign which doesn't appear to have/cause texture issues is the one with a
very...very simple introduction video(it doesn't have any moving objects) and
the original tutorial campaign.

All custom game maps I've tested seem ok.

Been looking for a workaround, but I haven't found a way to skip .the campaign
intros yet.

This is the same issue I'm experiencing:
http://heroescommunity.com/viewthread.php3?TID=38901&PID=1145057#focus

Unfortunately the described workaround doesn't work for me as primusrun on this
game causes a page fault.

Not sure which issue is more important...

I confirm this issue exactly with any engine versions from 1.3.3 up to 1.7.37.
I also encounter the bug sometime appearing after some turns in other
scenarios.
I can play  some turns but next scene  went to darkness.
It is not happen in real Windows so this is a bug of wine engine.
Tested in MacOSX with Heroes of Might and Magic VI Shades of Darkness v2.1.0
Water is always white place. It looks like an error with pixel shaders.
Videocard is Radeon HD6670.

They said workaround is to set Nvidia is always ON in its control panel.
In my case it is AMD Radeon HD6670 and the card works in host system. But it
drops into darkness in wine environment. Something like power management?
May be this observation gives someone an idea what is the bug?

log with trace+d3d_shader, uncompressed 453Mb

Still the issue with 1.9.10

I think the trace with shaders is the most relevant as I see the falling into
darkness occurred exactly in the same place on the map. It seems this place
described by wrong shader.
After the fall I normally exit the game by menu (it slightly visible) so the
log is not finished at the Fall.

Hope this observation will help a developer to say one word what it may be.
The game is unplayable because of this bug.

I looked the latest log, but it's too complicated for a common user to
interpret. Wine has received lots of shader compiler code since this was tested
last time. I don't know if it touches this area of code, but it would be good
to test.

Let me analyse again the origin of the bug.
Description:
1. The screen became dark after enter some scene.Easy to check with begin of
Crack Hack company. First scene id mostly black. Othe scenes looks normal until
you go to next scene. I have a saved game at some good place and I know if I
move camera to left then the screen will fall into darkness.
2. The darkness remains even you return into main menu. It will shown in darken
colors. Host OS works in normal brightness. It affectes on all wine drawing but
not on host OS.
3. You may change some video tunings in main menu which cause the game reload
resorces. It helps! The main menu will shown in normal brightness and you may
return to game with normal brightness until you enter again bad scene.
4. It is happen with Radeon and Nvidia, with Ubuntu and macOS so it is not
depending on host drivers.
5. There is one more bug related to the game bug 38621 and bug 39546 with
additional information. It is related to this bug because we always use native
d3dcompiler, the game is not working with builtin in wine one. But with builtin
compiler the brightness is always good!!!

So I propose that the game uses a shader in some scene which can't be compiled
with builtin d3dcompiler but this shader causes brightness problem if compiled
by native compiler. The question is to find the shader in 4Gb logs attached to
this bugs or suppose what is the error in d3dcompiler provided by wine.
As well it will be good to hear some explanations from people knowning shaders
language what is the possible reason for such brightness behaviour.

Sorry, my mistake. The bug exists even with builtin libraries. It is just less

wined3d: Do not treat  _SAMP_SRGB_TEXTURE state as a boolean value.

I tested the game from Ubisoft website (started by UPlay; basic package, some
campaigns look missing). The game worked right away with d3dcompiler_47 native
override only. I could reproduce the problem by starting "Dungeon Campaign"
("The Other Elves"). The screen gets dark during the intro animation, and after
that the map is dark on load. If I save the game, restart and load, or reset
device somehow (e. g. by changing resolution), the map is displayed nicely.

The problem is that at the start of intro animation the game sets some big
nonzero value (0x7e41882a) for D3DSAMP_SRGBTEXTURE (sampler 0). It does it
somewhere close to the end of frame rendering, and goes rendering next frame
with this value set. It sometimes switches D3DSAMP_SRGBTEXTURE to 0 for a short
while, but sets it back to the same value after, and most of the textures are
accessed with SRGB correction under Wine since that. Sampler state setting
looks exactly the same under Windows. The same sequence recorded and displayed
by apitrace displays without dark textures under Windows, and with those under
Wine. Ultimately disabling D3DSAMP_SRGBTEXTURE state handling makes it display
like on Windows.

Weird enough, Windows seem to not turn SRGB correction mode on when this value
(0x7e41882a) is used. I am attaching the patch which includes the test (which
succeeds for me on a Windows machine) showing that setting 2, 100 or that value
from the game trace does not make native d3d9 to perform SRGB correction. It
does that if the value of 1 is set.

The patch attached fixes the issue for me (tested on the campaign start
referenced above). The match introduces a comparioson of D3DSAMP_SRGBTEXTURE
value with 1 instead of treating it as a boolean value.

I don't think it is much likely that they are related. This bug is very
special. It is not quite common for games to request SRGB texture conversion on
sampling for no apparent reason, but go away with that because they set a non 1
value and it happens to have no effect on native d3d. At the same time, there
are endless possibilities for other potential issues which can effectively
result in textures looking darker or lighter.

FWIW after more testing I figured my patch is not exactly correct yet, but I
don't think it makes any difference here.

Is it some universally available map? I purchased some basic package from
Ubisoft website. If this is reproducible on some basic map, can you please
attach a gave save and some comment on what to do to see this? I will try to
reproduce. Or do you see it in every combat screen? I entered some combat on my
test campaign, and it looks ok. If you see it in every combat, there must me
some specifics with your setup, I would need your logs (ideally +d3d9,+d3d or
maybe at least +d3d9,warn+d3d), and your system details (OS / video card, exact
Wine version).

Testing many wine versions with or without staging patches and patches found on
the bugzilla. Result is mostly always the same with some additional bugs.
This bug remains to be the last stop to play the game.
The darkness is happen on the company of Captain Craig and sometimes on other
scenes. And always on the same place.
Now I checked other battle and see very good colors. Return to Captain save and
see bad colors again. Reloading resources doesn't help.

My game is from purchased DVD: Might & Magic Heroes VI Shades of Darkness
2.1.0.
I also have previous edition Heroes VI Gold Edition and it has no such bug. It
has a bug with increasing lags as well as on Windows. SoD works fine on Windows
7.

My system is macOS 10.13.6 with Xcode10,1. Wine compiled with SDK10.11 and
numerous MacPort libraries like libpng, libtls etc.
Nvidia GTX650 + hidden Intel HD530. I have to mention it because Wine see it as
well.
I will attach good screenshot for just other scenario but with the same wine.
Some minutes later a log with DEBUG.

Yes, it is first combat at the company of Captain Craig. The company is
available at the first start.

Log +d3d9,warn+d3d

There is wine-staging as of release 4.1 with some more patches. One of them
0037:fixme:d3d_shader:shader_glsl_get_caps Shader model 4. ->5
Wine determine Shader Model as 4, but I force it to be 5. It is not a problem
to set in registry MinShaderVS=4 or something else.

I restricted the log to 50000lines hope it contains needed information.
(Unpacked size was 1.7Gb)

Updated patch

> Too dark, much better then before.

I don't have Pirates of The Savage Sea campaign to test. If you can reproduce
it on Tutorial, Dungeon Campaign or Necropolis Campaign 2 I can take a look. Or
I even don't mind purchasing an unlock code for Captain Hack it asks for, but I
don't know how and I am done trying to figure it out with Ubisoft website. But
to be honest the chances it is reproducible for me on Linux are low. I reread
first few comments, they relate exactly to the Captain hack campaign and looks
like what my patch is fixing, while you might be having something different
now.

I am sorry, I have nothing to do with truncated log. Can you test with the
updated version of my patch? I don't have high hopes that it will fix it for
you if the first version did not, but it would be good to check.

In case the updated patch does not help, there is some chance I will see
something if I have the part which starts later. Can you please do the
truncated log which starts somewhere not so long before the problem exhibits
(e. g., after loading save, but strictly before going into the scene where you
see the problem. Like decscribed here:
https://wiki.winehq.org/Wine_Developer%27s_Guide/Debug_Logging (Controlling the
debugging output, that thing with pipe). Also could you please:

1. Use latest mainsteam Wine, no staging and other patches, preferably with my
patch from here applied (or without if this is a problem). Staging or anything
else should not be required for this game, the changes coming from there do not
make digging log easier.

2. If now log with truncated start will be much shorter, could you please try
it with both +d3d9,+d3d?

3. Which is your opengl version (glxinfo | grep OpenGL)?

It works without Staging. Please test with mainstream Wine (with my patch only)
and clean Wine prefix. Taking into account previous comments I think there is a
possibility that your problem might be related to your specific setup. In case
it still shows the same this way, maybe the log as I suggested may give some
more info.

saving game before fail

May be this saved game will show you the problem.
Unpack and place it into the folder
~/Documents/Might\ &\ Magic\ Heroes\ VI/reloaded/Save/
Run the game and load the saved game.
Just next turn will fall into the darkness.
It is not a company, it is single scenario.

I am working on creating pure wine with your new patch. But as I already said
the bug presents with all wine versions from 1.3 up to 4.1-xxx, with any
previous external patches with or without staging. It is not an issue of my
enviroment as well as I am not an author of this topic.

Will report soon.

That's all. Thanks Paul for your work and patience.

I reinstall 10.12 and clean my compilation. 
The I took wine-4.2 release and applied your last patch. No more.
I am still using native d3dx9 libraries (bug 38621).
The issue resolved. Colors are good in the saved game and in the Captain Craig
company.
Screen attached.

Have to mention that applying this patch to my previous wine-staging I got
reverse effect: the game started into darkness from the first intro. Even in
main menu. No matter. If this is my mistake then forget it!

When the patch will be accepted into mainstream this bug can be closed FIXED!

Fixed by 225fdc35586719406943286dd0e0d1aa8c25e3a1.

Just for the record, the same problem happens on Windows too. I could reproduce
exactly the same behaviour as before the fix on native Win7 using Intel video
card. I could also find some similar problem reports from Windows users. It
seems that on AMD or NVIDIA GPU this problem does not show up. The commit
replicates AMD behaviour in Wine in respect to _SAMP_SRGB_TEXTURE state (which
is different from NVIDIA in details).
