Started occurring in v66.0 on Windows 7 with Tk 8.5.

With Python 3.7 and Tk 8.6.8 it resizes and exits fine for me on Windows, but other users report problems with Tk 8.6 as well.

Issues also occur on Mac (Catalina 10.15, Tk 8.5). When resizing window it doesn't hang, but strange resize issues occur. On exit it crashes with this log messages:

Fatal Python error: PyEval_RestoreThread: NULL tstate
zsh: abort      python tkinter_.py

Stack trace for exit crash:

The hang when resizing window during initial loading is fixed in Tk 8.6, relevant commits in Issue #535.

Related issue in Panda3D project: panda3d/panda3d#586 . It states that disabling Panda3D message loop fixed the issue. So enabling CEF multi-threaded message loop may fix the issue as well.

Blocked by: #380 .
