I have "Animate windows when minimizing and maximizing" enabled in "Performance Options" of Windows 10 (probably, this option is enabled by default on most PCs).
When restoring a window which has Groupy tabs on its title bar, the tabs appear instantly, before the restore animation of the window is finished. So for a moment it looks like the tabs-bar just sits on my desktop attached to nothing.
It's usually noticeable and annoying, but I don't want to disable the restore-animation because of it.
I believe that Groupy developers can fix this issue just by adding a delay (about 500 ms.) before showing the Groupy tabs in case the "Animate windows when minimizing and maximizing" option is enabled.
I have Groupy version 1.21.
Example of the problem - Groupy tabs-bar appears before Notepad window is completely restored:
