Graphical artifacts
After a system update around Jan 4th 2020, yellow artifacts started appearing all over my screen.
I have set the AccelMethod
to uxa
as described in the Arch Wiki, and as a result most programs are without artifacts now. However the artifacts still appear in many GUI elements: In the window title bars, in lists for selecting stuff, and all over JavaFX applications. This is not only the case for my customised desktop, but also for the latest live boot media from Manjaro.
I tried uninstalling the Intel driver by sudo pacman -R xf86-video-intel
to use the modesetting driver, but the problem remained the same.
Because the setting of the acceleration method for the Intel driver had an impact, I suppose it is (also) a problem with the Intel driver, so I have decided to file the issue here, because the Intel driver is probably more common than the modesetting driver. Please correct me if I should file the issue at a different place!

Screenshot shows a custom JavaFX application and Dolphin in a customised KDE environment, the same effects also occur in a non-customised environment as on a fresh Manjaro live boot media. Note that the artifacts are for some reason in the desktop, the JavaFX application, and the title bars of most windows, but not in the content areas of the window for Dolphin and most other applications.
