Priority: medium
Bug ID: 70042
Assignee: dri-devel@lists.freedesktop.org
Summary: Major texture flickering in Dota 2
Severity: normal
Classification: Unclassified
OS: All
Reporter: alexandre.f.demers@gmail.com
Hardware: All
Status: NEW
Version: XOrg CVS
Component: DRM/Radeon
Product: DRI
Using a HD 6950 on Arch Linux 64
Using git codes for drm, mesa and ddx.
The game suffers from a major texture flickering in Dota 2. It has been since
the release of the game. I'll attach an API Trace later today and some
screenshots. It could be related to bug 68451, but the flickering is a lot more
important than the screenshots seem to indicate.
I could also test by disabling shaders's sb optimization.

We can cross off the board:

I can't seem to be able to launch dota 2 with apitrace. I can launch Steam, but
Dota keeps crashing at launch. I'll add screenshots later.

Visible corruption on mini-map
While the texture flickering is very fast, it appears as static on screenshots.
On this one, textures flickering on the mini-map and a thin artifact on the
left side of the screen (looks like a line, but it is most likely a triangle
caused by the light coming from a tower)

Here, some more visible glitches flickering at an impressive pace.

Here is a link to a video exhibiting the corruptions/glitches.
https://docs.google.com/file/d/0Bw_tZdWsNa4BN0ZmRy1DMnFKZWs/edit?usp=sharing
You'll notice glitches here and there, mostly triangles. On the minimap, on the
player's face and on some elements (name or HP), it is really visible. Working
on an api trace (I have a trace, working on trimming it down).

Marek, should I continue with the API trace if the patch fixes the flickering?

I don't know the impact on performance of attachment 87165. Dota 2 was the only
game I was experiencing this texture flickering. It would be interesting to
understand what and why. Anyway, it fixes the issue, so closing this bug.
