Bug #: 31493
           Summary: Dota 2: hero tooltip text is not rendered
                    apprropriately
           Product: Wine
           Version: 1.5.11
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

Created attachment 41401
  --> http://bugs.winehq.org/attachment.cgi?id=41401
Corrupted tooltip above Mirana

Repro:
1. Start/watch dota 2 game
2. Hover cursor over hero
3. Observe tooltip which appears above it

Result:
Tooltip text is not shown, see screenshot. As you play game, some letters may
randomly appear there (correct letters in correct positions, but they don't
appear one-by-one from left to right or all together).

Expected:
Tooltip should show hero class and hero level.

Forgot to mention that this bug is relatively new (appeared ~1-2 months ago)
and were introduced with some dota2 update. Disabling dwrite.dll in library
overrides doesn't help.

This bug is probably very similar to the issues I've seen with Team Fortress 2,
where text is randomly missing. It appears to be less serious in Dota2 (maybe
because it's a newer game and Valve has done something to resolve it?), and
only appears in tooltips.

I'm unable to actually find a bug report for the Team Fortress 2 text issue,
though there are a few mentions of it on the Team Fortress 2 appdb page.

It is my educated guess that this is the same problem which affects other
Source Engine games. In the source engine, if you do not take advantage of
multi-core rendering in the current build of wine, then source engine games run
pretty much without any rendering glitches (with the exception of minor stuff
like black blotches on the textures of health and ammo pickups in TF2). As soon
as you enable multi-core rendering however, you get a nice FPS boost, but at
the cost of lights sources penetrating walls and wonky text rendering. Dota 2
takes advantage of multi-core rendering by default, and of course the first
problem doesn't exist in dota because there are no walls, the text still
rendering wonky.

This isn't a dota-specific bug, but rather a bug with the multi-core renderer
in the Source engine.

Just to make this clear, it's gotta be a bug in wine causing malfunctions in
Source's multicore renderer -- I'm quite sure that it's not a bug in the
engine.

However, both issues mentioned here (i.e. "penetrating lights" and "invisible
tooltip text") *could* be caused by some kind of missing synchronization
between two rendering threads, so things are rendered in the wrong order. That
is:
- Lights after geometry obscuring them
- Some letters in tooltips prior to the tooltip's background

But after all, these issues being related is just a guess...

Moreover, debugging this might be really horrid: I assume it would come down to
comparing d3d/d3d9 traces between single- and multicore rendering mode. That's
a *huge* bunch of data and manual work... and I'm not too sure this approach
could succeed at all.

The issue with the lights is caused by occlusion queries not working across
threads, and just giving wrong results in that case. This causes lights to be
rendered that are supposed to be occluded. I don't know for sure if the tooltip
issue is the same bug or related, but it's not an unreasonable assumption. We
have other known issues with multithreaded D3D as well though. Some of those
can be worked around with the "StrictDrawOrdering" registry setting, though at
a significant performance cost.

This indeed fixes the issue for me, at an FPS cost of ~10% -- which is totally
acceptable in my case. The game still seems to run more smoothly compared to
running it with -nod3d9ex. Thanks for the hint!

Can anybody confirm? If so, this workaround could be worth mentioning in the
HowTo section.

My apologies, I gotta take this back... in greater clashes with lots of effects
my FPS drop to about ~15 (which is about -60%). So I guess either
- playing with -nod3d9ex and accepting lag spikes when new stuff gets loaded,
or
- playing without -nod3d9ex but having broken tooltips/nameplates
are still the ways to go until we got threaded occlusion queries.

Btw, I'm just curious: Are there any plans on this?

Allowing occlusion queries to be shared across contexts would require a GL
extension. We have been considering some wined3d changes that would avoid the
issue for some time now, but it's a non-trivial change, with questionable
benefits.

This can be worked around using a console option. Add -console to Dota 2's
launch options, then type this in the console:

mat_queue_mode 0

This fixed it for me.

I've just find out that you can workaround this bug by clicking few times on
top left arrow-button. so no performance will be lost)

When I play for example using warlock, I cannot see nothing under the box where
reads the title of your warrior. I think I should see there some face
movements?

ANd when I die you see who killed you, I cannot see there nothing but void
screen.

This is your friendly reminder that there has been no bug activity for over a
year. Is this still an issue in current (1.7.51 or newer) wine?
