Moving GTK apps mostly off-screen on the right or bottom screen edges makes the window disappear

[git-f0x]

When a GTK app window (including Firefox) is moved past the right or bottom screen edge so that most of it is off-screen, the app window disappears past a certain point and reappears when going back or dropping the window. This issue was present for a while, but can now interfere with the tiling regions. Recording of the issue:

Are you on the latest commit 929f4fcb054710ee73d781f7050f0a005981fa0e ?

[git-f0x]

Yes. It was present for a long time, not related to any recent commits.

Wanted to make sure the newest commit didn't fix it

Now GTK apps seem to also disappear when dragged in tiling mode.

I can't reproduce this (at least with Firefox and Nautilus), so I'm not sure if it's dependent on some settings or hardware.

I can't really test it right now since I don't have access to my PC until Monday, this may have been resolved while I was away. I'm using AMD CPU+GPU combo, so I'm not sure it's a driver issue.

The issue I reported seems to be unrelated to this, but instead to export of themes to GTK apps, when the given COSMIC theme contains has background alpha < 1. Since you can't edit transparency in COSMIC Settings -> Appearance right now and instead have to edit the themes .ron file directly I can't expect it to work now as it's not a "feature" yet.
