Alternatively update the applications.
The problem is that the driver exposes 10bit RGB and the applications selects that for some reason but actually can't handle it correctly.
Could you please confirm that it is a bug of application and not Mesa?
Please see the other bug report. This is actually not a problem related to the driver or Mesa in any way. The xserver just exposes 10bit color config on AMD now and some applications doesn't seem to correctly handle those.
I had an argument with my favorite distro's maintainers on this, and their point is that other drivers (intel and nouveau) don't have this problem. Do these drivers even expose 10bit color configs?
Not sure, but that can indeed be the reason they don't show those problems.
