it's a *top* panel, right?
Comment 2 Nicolas Fella 2022-01-20 13:58:40 UTC 
Is that on X11 or Wayland?

I meant under panel (more likely *bottom*)
Comment 4 David Edmundson 2022-01-20 14:01:26 UTC 
Can reproduce with a top panel and gtk4-demo. Any CSD apps will still snap correctly, but can be moved beneath it, SSDs apps will stop moving at the boundary
