I have the same issue since I updated earlier today. It seems to work fine when I use 6.14 kernel but starts happening on 6.15. Can confirm issue; 6.14 kernel works fine, 6.15 kernel has gray rectangle flicker below cursor. Dual monitor setup; one monitor 1080p, the other 4K. Occurs in both XOrg and Wayland. AMD GPU 7900 XTX. Can confirm as well. For me there is also occasional severe flickering of the entire screen though. Booting into a 6.14 kernel seems to work around this issue. I'm using Wayland on a Radeon 7900 XTX.

For me, downgrading just linux-firmware to 20250311-1.fc42 on its own does not fix it. I also have to use kernel 6.14 as well to avoid the glitches.

The package that contains the GPU firmware is amd-gpu-firmware, the base linux-firmware contains other generic firmware so if you just did that I wouldn't expect that to fix it. Ah, I didn't know it was split. Oddly enough, downgrading amd-gpu-firmware also doesn't fully fix it. Either I'm doing something wrong, or there's also a kernel bug. there's probably kernel bugs too, but did you rebuild your initrd to ensure the right firmware is in it? Ah, that's what I was missing, I thought installing the package did that already. After rebuilding the initrd, downgrading does indeed fix it. The kernel package does that On my AMD 5600G system which has integrated graphics, running F42 KDE, Wayland and kernel 6.15.3-200. I cannot repro the issue. If that helps.
