[BUG] Slow and lag when focusing Unreal Engine

[Deewens]

Describe the bug
I just tried the app, and it seems really great, thanks!
However, I played around a bit with it, and the Dock animations are slow and laggy when focusing the Unreal Engine editor. I know that UE is already not the greatest software when it comes to integration within the OS, and sometimes it behaves very weirdly, even with the native windows' taskbar (like if I set the taskbar to auto-hide, I cannot unhide the taskbar if Unreal Engine is focused and fullscreen). It seems to be the same, if Unreal Engine is full-screen, then Seelen Dock is "slow" to unhide, and animations when hovering on the apps are slow (at least it can unhide which is still better than native Windows taskbar). However, it only seems visual (apart from the slow "unhide"); I can still click on apps in the dock, even though the animations did not catch up.

To Reproduce
Steps to reproduce the behavior:

1. Open Unreal Engine Editor
2. Put it in full screen
3. Try to unhide the dock
4. Try to hover on the applications of the taskbar and click on one of them

Expected behavior
The dock should behave as usual, no lag or slowness.

I think this will happen with any program that hard use graphics, like video editors too. I don't know if giving priority to resources could fix this. Could you try it?
