It'd be be great to have this merged, there are graphical corruptions with the mesa version in FDO 21.08 (they can't upgrade to newer mesa which fixes it as mesa removed support for a lot of drivers). Electron applications are primarily affected. With 21.08, the solution is to use mesa extension from flathub-beta.
