Flicker when changing focused window with Komorebi #379

Open Insprill opened 5 months ago

Insprill commented 5 months ago

When Komorebi (a tiling window manager for Windows) is running, all JetBrains IDEs suffer from severe flickering when changing the focused window, including popups in the IDE itself.

This is fully reproducible, and others have confirmed it on Komorebi's issue tracker: https://github.com/LGUG2Z/komorebi/issues/781

This is only an issue when using JetBrains' runtime. I've tested Adoptium and Graal 17 and 22, and neither suffers from flickering. Both versions of the JetBrains runtime I tested (17 & 21) do.

Here's a video of it happening:
