--- Comment #55 from Wassim Akkari <wasso...@live.fr> --- It's very random I have to kde systems one Fedora witch doesn't suffer from the vertical or horizontal colored line but has the pixel gap in XWayland apps, The other one is CachyOS (Arch Linux) which has the colored line bug on steam, and some glitches with small blinking lines on other XWayland apps. I have Legion5i Pro (i7 12700H) NVidia 3060 Mobile and driver is the latest 555 on both systems with the latest KDE version 6.0.5 I also noticed some difference when I let XWayland apps when display setting is set to "Scaled by the system" the issue occur on VLC, Steam and even my Binance client app. When I change it to "Apply Scaling themselves" the issue appears less it only remains on steam (it changes to a horizontal colored line instead of vertical) and I still have some glitches of blinking white lines in other apps like vlc but not the full vertical colored line. Could you try altering that setting, make legacy apps "scaled by system" and leave scaling to 150% or try with different scaling and close steam and vlc and open them every time and test. -- You are receiving this mail because: You are watching all bug changes.
