Bug ID: 203471 Summary: Tearing on Raven Ridge and RX560X PRIME setup even with Vsync enabled Product: Drivers Version: 2.5 Kernel Version: 5.1 rc6 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: haxk612@gmail.com Regression: No
I have Acer Nitro 5 AN515-42 with Ryzen 5 2500U and RX560X. When i launch some game with DRI_PRIME=1 to have it on dGPU there is huge tearing on top of the screen that is there with or without Vsync. If i launch the game on iGPU there is no tearing at all. Also the tearing happens only when the game is in fullscreen. If i take a screenshot there is no tearing in the screenshot. And i cannot post a picture as my phone camera is broken in my latest build of android. I have tried 5.2-wip branch and there is the same issue. Will post dmesg and journalctl in few hours.
