https://bugs.freedesktop.org/show_bug.cgi?id=102358 --- Comment #11 from haro41@gmx.de --- i applied your patch successful, still the freezes, maybe in average a bit later now. The behavoir changed a bit: before patch: vblank_mode=2 (default)-> always freezes inside 0..2 minutes runtime, framerate fix/clamped at 50(as expected) vblank_mode=0 -> no freezes at all, dynamic, high framerates LIBGL_DRI3_DISABLE=1 -> no freezes at all, framerate fix at 50 after patch: vblank_mode=2 (default)-> always freezes inside 0..2 minutes runtime, framerate fix/clamped at 100(!!) vblank_mode=0 -> no freezes at all, dynamic, high framerates LIBGL_DRI3_DISABLE=1 -> no freezes at all, framerate fix at 50 To be honest, i am not familiar enough with DRM internals to understand what exactly happens here, but it looks like something is broken in respect to DRI 3 usage. Somehow i think i could be the only one with this freezes and to ensure i am not wasting your time: Can you give me a hint, where i should look first to exclude it is something specific to my system/setup? -- You are receiving this mail because: You are the assignee for the bug.
