[Bug 35749] New: Screen update problems on Counter Strike: Global Offensive
http://bugs.winehq.org/show_bug.cgi?id=35749 Bug ID: 35749 Summary: Screen update problems on Counter Strike: Global Offensive Product: Wine Version: 1.7.14 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: directx-d3d Assignee: wine-bugs(a)winehq.org Reporter: gediminas(a)varciai.lt CC: ken(a)codeweavers.com, stefan(a)codeweavers.com Regression SHA1: 4c4552c5a1910a9d5adf8eccff0ac62d89ffe376 A new regression: While playing Counter Strike: Global Offensive (other source engine games might also be affected; did not test yet), it runs fine at first, but if I alt-tab out of it and back several times, the game starts stuttering a lot and the *apparent* framerate drops several times. Even though it looks as if the framerate plummeted, the in-game FPS counter keeps showing a normal framerate, i.e. there is no framerate drop from the game's point of view. GPU load also remains the same, too. Thus, this leads to believe that rendering is still done normally, but Wine doesn't flip / update the screen properly, leading to stuttering and apparent framerate drop. After some testing, I found that reverting this patch makes the problem go away: commit 4c4552c5a1910a9d5adf8eccff0ac62d89ffe376 Author: Ken Thomases <ken(a)codeweavers.com> Date: Wed Feb 19 16:14:53 2014 -0600 wined3d: Restore the pixel format of the window whose pixel format was actually changed. I also tried it with the patch from bug #35705 - It did not help at all, so it is possibly a different bug. Judging from its description, it does not seem that bug #35655 would the same bug, either. With the bug triggered, I did not see any errors / warnings / fixmes that were not present with the bug NOT triggered, even with +d3d on. So, I am not sure whether posting debug output would be of any use. Although it in itself is unsupported, to shed more light on the matter, I should also mention about the behavior of this bug when encountered on Wine with Stefan Dösinger's CSMT patchset: Everything is the same, except the game is stuck on showing one frame that was drawn right before triggering the bug. Which *visually* makes it seem as the game has hanged. Leaving game like this for longer amounts of time, I can see that it then flips / updates the screen approximately once every one minute [leading to 0.016 frames per second, effectively]. Sometimes, after waiting a minute or two, graphics start updating / working normally again, but that lasts for fifteen seconds tops and it gets stuck on showing one frame again. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

http://bugs.winehq.org/show_bug.cgi?id=35749 --- Comment #2 from Gediminas Jakutis <gediminas(a)varciai.lt> --- Okay, I retested: With attachment 47758 from bug 35718 on latest git (did not apply attachment 47706 from bug 35705 as it appears to already be in the latest git), there's a bit of change - on top of stuttering and apparent framerate drop, the game now sometimes instead just "visually hang" in the same manner as it does with Stefan Dösinger's CSMT patchset. Meanwhile, on Wine with Stefan Dösinger's CSMT patchset, I observed no change in behavior. TL;DR – those patches did not help at all. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
