Issue description

After a while application windows stop drawing or responding. I can switch to them, but they are just a frame, the application is not rendering on screen Only solution is to kill them

Observed this issue with the following applications:

1. Chromium
2. Webmacs (consistently after while of usage)
3. Slack (ocassionaly after swithing around or some window events)
4. Discord (most reliably when switching groups)
