Chrome 72.0.3595.2 (Dev) on Linux can get into a state when it stops redrawing:

Facts:
- Chrome was running fine since Wed Oct 31 13:17:59 2018 (~5 days)
- Notifications (e.g. from chat.google.com) would still pop-up, but they would "paint white"
- The problem affected all Chrome windows.
- Could drag the window around, it just wouldn't repaint.
- Killing the gpu process made things work/paint again (first child of the main Chrome process that had --type=gpu-process;  the killed process had a few children of its own - all of them also with --type=gpu-process;  "killing" = sigterm)
- No high CPU or memory usage was observed.
- After attempting to focus a broken Chrome window, I tried pressing 
 Ctrl-N and AFAICT it didn't have any effect.
- chrome://gpu says:

No known repro steps.  Maybe using Gerrit?  Maybe dragging/repositioning the window?
