Oni: Flicker due to changing themes

[tcoopman]

Oni: 0.3.4
Platform: Archlinux

Problem: when going back and forth between switch themes, at some point the background color begins to flicker. If I then close the theme dialog everything keeps flickering until I restart oni. Sometimes it stops when I change the theme again.

Happens both with canvas and webgl renderer.

I can confirm I've seen this happening before on Windows too.

I've never managed to nail down what is causing the issue as it doesn't seem to be due to swapping between two certain themes, just after some time it happens.

I've had this happen too, usually when cycling through the themes menu. I think the themes menu should be changed so it only changes themes on enter keypress instead of cycling the menu. Another issue is that the first entry in the menu can't be selected unless you go down and then back up again.

This happened to me when trying to change themes via the themes command. The only way to get it to stop is by restarting oni. Oni version: 0.3.4 on macOS
