FancyZones steals input focus on display resolution change which breaks fullscreen games

Environment

Windows build number: 10.0.18362.295
PowerToys version: 0.11.0
PowerToy module for which you are reporting the bug (if applicable): FancyZones

Steps to reproduce

Ensure FancyZones is active. The option “Flash zones when the active FancyZones layout changes” may need to be enabled as well.

Run any fullscreen game which uses a resolution different from the desktop resolution.

I first noticed this on Spyro: Reignited Trilogy for PC but then made a simple Unity project to confirm it’s nothing specific that game is doing. I have attached it below (source code and binary) to allow for easy reproduction.

Test.zip

The resolution selection dialog has been enabled for the included build. Disable “Windowed” and select a resolution different from the desktop resolution.

Expected behavior

The game runs as it normally would.

Actual behavior

FancyZones attempts to display the zones in the new resolution, stealing focus from the game. This causes Windows to minimize the game and revert to the previous desktop resolution. It is impossible to maintain focus on the game.

After closing out of PowerToys the game can be restored and runs normally.

Yup, seems to work fine.
