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-...@kernel-bugs.osdl.org
Reporter: haxk...@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.
