Boot with Linux 6.19.4 (or any 6.19.x) 2. Start X11 session (XFCE via startx) 3. Launch Nioh 3 via Steam Proton (default settings with VSync OFF or ON) 4. Move the camera/viewport vertically =E2=86=92 observe horizontal tearing= lines **Workaround that eliminates the tearing** Create or edit: /etc/X11/xorg.conf.d/20-amdgpu.conf ``` Section "Device" Identifier "AMD Graphics" Driver "amdgpu" Option "TearFree" "true" EndSection ``` However, it introduces a small performance overhead or input latency. On 6.18.9, no such configuration was needed. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
