I am also on openSUSE Tumbleweed, but using Flatpak Firefox.
Perhaps you can try disabling hardware acceleration in Firefox to see if it chinges anyting.
I’ll give it a shot. I don’t use flatpaks, but I think I’ve already disabled hardware acceleration for a previous issue? I’ll report back once I’ve checked/tried it out.

Reporting back, you were absolutely correct. Hardware acceleration was turned back on, and turning it off fixed the problem.
