I found I was able to cause this hang reliably, and that it could be fixed by
setting the compositor to xrender, both OpenGL 2.0 and 3.1 have this bug.
The trigger I had was alt-tabbing, and it seems to only trigger for some
programs. It was very reliably triggered when alt-tabbing into and out of
Terminator, and seems 100% reliable going from Chrome into Terminator.
(Thought: could this be GTK related?)
Potentially relevant settings?:
compositor - animation speed one step above instant
compositor - full screen repaints
compositor - keep window thumbnails only for shown windows
task switcher - "show selected window" is ticked
task switcher - visualization is "Compact"
software:
KDE Neon, up to date.
hardware (separate systems, same physical hard dive):
Dell 5491 laptop, nvidia mx130 - Maxwell - very similar to original report.
Thinkpad w530 laptop, nvidia k1000m - Kepler - architectural generation behind
original report.
I've tested these drivers from the third party drivers PPA for nvidia
(ppa:graphics-drivers/ppa):
390 (available without ppa): exhibits bug
418: exhibits bug
(This is my first post, please let me know if I need to include anything/read
through some guidelines...)
