Incorrectly renderer login screen

Fedora 24 has just upgraded Wine from 1.9.20-staging to 1.9.22-staging. And now
some text is rendered to the screen incorrectly.

I have attached a screenshot; the overlarge text is supposed to have been
rendered in the "Breaking News" window.

This problem happens in DirectX 9 mode, but not in OpenGL mode. However, OpenGL
mode is unplayable anyway because Blizzard released it without testing it
properly.

Hi, Chris. I have pushed a 1.9.23 build to updates-testing if you want to see
if the issue is fixed there.

Screenshot showing incorrect rendering

The problem seems to happen when rendering to "in-game windows". The large
black circle dominating the screenshot is the game's minimap, which *should* be
rendered within the circular frame in the top-right corner.

I'm using the same version on arch Linux and I didn't have the issue. 
However there are other users having the issue that the 64bit client freezes.

Are you using Radeon graphics with Mesa? Or NVIDIA graphics with binary blob?

I have managed to test this on a laptop which has hybrid Broadwell/NVIDIA
graphics, and can report that Wine does indeed behave correctly when using
NVIDIA's driver. However, the bug still happens with Broadwell/Mesa.

The difference between the Wine output with each driver appears to be that
Broadwell/Mesa generates log lines like these:

err:d3d:wined3d_debug_callback 0xed9a20: "GL_INVALID_OPERATION in unsupported
function called (unsupported extension or deprecated function?)".

Could you find out what function that is? If there are no hints in the log, the
easiest way to find that out may be to put a breakpoint on
wined3d_debug_callback() and get a backtrace when it triggers.

After this point you have to type "c" to make the program actually run.

Thank you, but I can actually tell when a program is running and when it isn't
:-|.
I'm suspecting that debuginfo-install is only installing the 64 bit debug
symbols, rather than the 32 bit symbols that winedbg needs.

And to cap it all:

WineDbg starting on pid 0030
fixme:dbghelp_dwarf:dwarf2_swallow_attribute Unhandled attribute form 1f21

So winedbg doesn't work for 64 bi and crashes for 32 bit. I'm all out of ideas
here.

Whatever this bug is, it requires Mesa also to support OpenGL >= 4. Which means
that WoW will work correctly provided I set the following environment
variables:

MESA_GL_VERSION_OVERRIDE=3.3COMPAT
MESA_GLSL_VERSION_OVERRIDE=420

(This is for my Radeon R7 360, which supports OpenGL 4.5 with the latest Mesa.)

WoW only really requires OpenGL 3.3, although I think some of its shaders
demand GLSL 4.2 support. So "under advertising" OpenGL support is a
work-around.

I'm curious, can you check that you're not running with the d3d11 renderer
(that's the "Graphics API" setting under System->Advanced)?

You normally run the game without Mesa version overrides and that fails as in
the bug description, right?

Can you please attach the plain terminal output with no overrides?

No, I've been running WoW with MESA_GL_VERSION_OVERRIDE for a while now so that
OpenGL mode wouldn't crash:

https://bugs.freedesktop.org/show_bug.cgi?id=91600#c5

However, then Blizzard made a half-donkeyed effort to update OpenGL mode that
left it unplayable. And D3D11 mode doesn't work yet either, so D3D9 mode it had
to be.

Well, don't run Wine with Mesa version overrides, that's not a supported
configuration and it might explain the bug.

So if I understand it correctly, WoW works fine for you with d3d9 and no
overrides? If that's the case there is nothing to fix here.

Not setting MESA_GL_VERSION_OVERRIDE sounds like just another workaround to me
:-|. Because as I've already said, it also works with
MESA_GL_VERSION_OVERRIDE=4.0COMPAT.

For reference, Warcraft's OpenGL mode *still* crashes unless
MESA_GL_VERSION_OVERRIDE=3.3COMPAT or better. (It complains that it cannot
activate 3D acceleration).

How is not setting any override a workaround?
Wine, like any reasonable OpenGL application, checks what features are
available with the current driver / GPU and uses only those that are supported.
If you override the GL version reported by the Mesa driver you effectively
break that kind of checking, since the driver now reports a bunch more features
as supported which they really aren't (that environment variable doesn't
magically add features to the driver). Wine goes to use them, they don't work
and you get GL errors and broken rendering.

By overriding the GL version to 4.1 compatibility you enable a number of
extensions flags in Wine without the driver being able to support them,
breaking things. FWIW it's probably ARB_viewport_array the relevant extension.

That would be a separate bug. There isn't anything we can do if Warcraft
requires an OpenGL 3.3 compatibility profile, Mesa just doesn't support that.

Except that I have a Radeon R7 360 that supports OpenGL *4.5* with the latest
version of Mesa (which I am running). So "yes", I expect Wine still to work
correctly when I *downgrade* to OpenGL 4.1.

Which radeonsi supports. So what's your point?

I meant to insert a "though" after "profile"... Anyway, OpenGL being broken for
you with Mesa + the version override is not surprising, with that you're just
hacking the driver to pass the WoW GL version check.

It supports OpenGL 4.5 only with core profile. You're forcing compatibility,
which is a separate thing.

Only in core profiles.

For the records, Mesa reports GL 3.0 in compatibility profile.

It reports GL 3.0, except with lots of other extensions available too (e.g.
ARB_sync). Otherwise WoW's OpenGL mode would still crash despite my setting
MESA_GL_VERSION_OVERRIDE=3.3COMPAT.

But not ARB_viewport_array, which is the likely reason for this bug report.

In Mesa there are a number of 3.1+ extensions / features which are only
implemented for core profile. There is a reason why the reported version is 3.0
in compatibility profile and overriding the version is generally going to break
stuff.

I'm sure there might be some applications for which a version override might
work good enough, but that's the exception, not the norm.

I think what worries me even more here is the implication that Wine doesn't use
core profiles for its DirectX emulation. That doesn't bode well for Mesa users.

That is bug 38648. We're working on it, in the meantime you can set the
MaxVersionGL registry key to try that out. Just remember to mention that if you
are to report bugs with the key set :)
