I considered a hardware problem, but that seems unlikely for many reasons: The
video card is still very new (about an year now) and a solid Gigabyte model...
I've had another Radeon / Gigabyte card before it, which lasted me for nearly a
decade. This issue is also triggered only by the KDE desktop, when certain
desktop effects play or I select some windows (even with effects turned off)...
I play high-end games on my machine, yet even they don't trigger this exact
crash! The behavior of the crash also closely indicates a software problem...
hardware issues usually cause a total freeze (Kernel panic), whereas this only
freezes the desktop (without mouse pointer) then causes the monitor to shut
down.

I have a report there as well, mirroring this one:
https://bugs.freedesktop.org/show_bug.cgi?id=100306 Since only windows in KDE
seem to trigger this specific crash, I'll probably make a third mirror on KDE's
bug tracker as well... need to consider if it's related closely enough to KDE
for that.
