Created attachment 89078 [details] Screenshot of buggy rendering For awhile the intel driver has failed to render the game, Space Pirates and Zombies (SPAZ) correctly while running in a window while SNA is enabled (switching to UXA resolves the issue). The game renders fine in fullscreen, but less half of the viewing area renders when the game runs in a window. Screenshot attached.
Please attach your Xorg.0.log.
Never mind. I'm an idiot. After gathering up the log information I noticed that the Steam client was producing log entries while attempting to turn on it's in-game UI. Turning that off resolves the issue. This must be a specific issue related to Steam itself rather than the driver as this doesn't cause a problem in other games. My apologies.
Excuse me whilst I just play SPAZ for a day or two to confirm that I can't reproduce the bug...
Ok, let's treat this as a Steam overlay issue until proven otherwise.
