Comment 103 for bug 1814125

Doing some more testing on the desktop system, this now gets weird and weirder. My desktop is also effected by this, just not when running glxgears, I bought a bluetooth dongle to have the circle animation.
gnome-shell cpu usage:
Threaded swap wait enabled - Desktop:
glxgears - normal, no cpu spikes
g-c-c bluetooth animation - 85% cpu
dragging windows - 85%cpu

Threaded swap wait enabled - notebook/PRIME:
glxgears - normal, spiking to 85% cpu
g-c-c bluetooth animation - 85% cpu
dragging windows - 85% cpu

Now setting __GL_MaxFramesAllowed=1 on both systems:
desktop: no change! cpu usage still high (?)
glxgears - normal, no cpu spikes
g-c-c bluetooth animation - 85% cpu
dragging windows - 85%cpu

notebook:
glxgears - normal, 10% cpu, no spikes
g-c-c bluetooth animation - normal, 10% cpu
dragging windows - okayish, 35% cpu

Next I'll check if the mentioned patch changes anything.
