LLVM 7.0 and MESA 17.4 + Wayland = broken mouse control
After updated LLVM and MESA in repo https://copr.fedorainfracloud.org/coprs/che/mesa/
- LLVM: 7.0.0-0.1.r322132
- MESA: 17.4.0-0.16.git41c36c4
mouse hover are stop working on all controls. It means I unable launch application by clicking on application icon also I unable drag and resize windows. And all controls are not clickable. But keyboard works fine.
This problem only happens with AMD GPU. Intel GPU not affected by this bug.
AMD developers said that sounds like the known gnome-shell/mutter bugs related to 10 bits per component colour formats.
And Marek's position in mailing list is to keep Mesa as-is, leaving gnome-shell broken, so that gnome-shell developers are alerted and fix their code. If we react by removing 10bit support from drivers, the odds are gnome-shell will never be fixed and drivers will never be able to have 10bit support in them.
$ gnome-shell --version GNOME Shell 3.26.2
