Grid disappears ever other keystroke

[dylon]

When I launch keynav, the grid disappears every-other keystroke. The issue has been reported by another user in the following issue:

NixOS/nixpkgs#30160

Below are the relevant specs for my laptop that may help, let me know if you need anything else:

• Arch Linux (distro)
• Linux kernel v. 5.1.4
• KDE Plasma v. 5.15.5
• KDE Framework v. 5.58.0
• Nvidia (proprietary) graphics driver v. 430.14

The problem seems to be with the flickering prevention algorithm in update. If you comment out XUnmapWindow at https://github.com/jordansissel/keynav/blob/master/keynav.c#L1422 it works.

Same problem here with the Awesome WM and commenting out the XUnmapWindow works.

This XUnmapWindow was to prevent flickering? But I no longer get flickers after commenting out it!
