Before deadlock, nothing is printed to terminal. I've also attempted using GALLIUM_HUD environment variable to display various information. There's nothing unusual right before deadlock (no VRAM usage spike, no high GPU load, etc). Deadlocks seem to be completely random (I see no relation between scene complexity, CPU load, etc). I.e. it may deadlock both on idle scene and during active physics simulation (in case of Tabletop Simulator). Looks like an AMD GPU issue. If additional info is needed, let me know. This could be a duplicate of bug 97174, try the LD_PRELOAD / LIBGL_DRI3_DISABLE workarounds described there. |

I've been experiencing problems with open-source AMD GPU driver and specific OpenGL applications. Particularly, Tabletop Simulator and Left 4 Dead 2 exhibit this behavior. After a few minutes since game launches, it (apparently randomly) deadlocks, screen stops to refresh. If game is minimized and maximized again, it will show black screen. From this state, it could only be closed with SIGINT in terminal or SIGKILL. Left 4 Dead 2 has similar issue, but unlike Tabletop Simulator, it doesn't seem to deadlock in main menu. My configuration: Gentoo Linux Dual AMD Radeon RX 480 (Polaris 10). 4.7.0 kernel with AMD GPU built as module (PowerPlay component enabled). mesa git (9999). xf86-video-amdgpu git (9999).
