1 month ago I have the same issue on my system with an RX570 card, even with my environment limited to WindowMaker and XScreenSaver. DRM version is 5.15 here:

Title: X11 unusably slow with DRM 5.15 and 6.1's amdgpu on a RX 800
Description and reproduction
With DRM 5.15 running with an AMD RX 800 card, after a few minutes to hours in a X11 session, just clicking on a program in the task bar to switch to it or using Alt-Tab can freeze the whole display during seconds. Generally speaking, any kind of desktop effect (such as application thumbnail display when hovering over the task bar) is slow. As the uptime progresses, freezes tend to last longer (I've measured that a few of them lasted for almost 10 minutes).
DRM 6.1 has the same problem but in a slightly lighter form: It takes more uptime for the problem to start manifesting, and freezes are initially shorter. However, they increase over time to the point that the desktop eventually becomes almost unusable, as for 5.15.
DRM 5.10 works correctly. This problem also doesn't show up on some laptop using Intel Gen10 integrated graphics (driver i915) with DRM 5.15 and DRM 6.1 (although another problem shows up, to be reported separately).
Tested mostly with KDE/KWin, but Xfce has similar problems. Turning off composition in KWin essentially doesn't solve the problem (barely makes an almost imperceptible difference).

Preliminary Investigation
Before clear, long freezes, it is common to observe, after some uptime, Xorg using ~5% CPU for several seconds or more. Some captured kernel stacks:
The frequency of the stacks with
ttm_pool_free()at the bottom increases as small glitches and freezes appear (not reproduced below). Other stacks that were captured much more rarely:Finally, outputting kernel stack traces every 0.1s during freezes seems to indicate that the process is stuck in (or repeatedly calling):
This stack also appears, although less frequently (it's in fact a sub-stack of the previous):
