@stedekay Can't reproduce this, which window manager are you using? Also are you using X11 or Wayland?

[stedekay]

I'm using the default of Ubuntu, so "Gnome Shell" I guess? And I am using Wayland.

I made a short video of my right screen, starting with Mattermost on left screen. I then toggle between minimizing and reopening it. You can see a (tiny) difference on the left (only visible when you maximize the video player).

I know this is very knitpicking, maybe it bothers me more than it should 😃
