--- Comment #46 from Duncan (1i5t5.duncan@cox.net) --- (In reply to Fabian Möller from comment #45)
Applying 6eb3cf2e06d22b2b08e6b0ab48cb9c05a8e1a107 to v5.7.7 fixed the issue for a RX5700/Navi10 under Wayland for me.
Polaris11 uses a different code path or needs an additional fix? (Less likely, maybe X/plasma/kwin makes the kernel calls differently?)
Progress for all and a fix for some in any case! =:^)
