--- Comment #1 from Jimmy Berry (jimmy at boombatower.com) ---
Looks like I have the same thing on 5.14.6 with a Radeon 6900 XT.
>From 5.13.8 I was able to run 4 x 4k @ 60hz + 2 x 4k @30hz. Hardware should
support all 6 at 60hz, but that is all I can get to work. As of the update to
5.14.6 I can now only run 3 x 4k @ 60hz + 3 x 4k @ 30hz.
Wondering if this error is related. I can supply more detail.
