Image showing the gap between the cursor texture and the highlight button
SUMMARY
I'm on KDE 5.26.4 [Fedora], and I've a weird issue with Unreal Engine. The
mouse pointer has an offset between the mouse texture and the actual mouse
hover/click point.
This bug only show in Unreal Engine Editor, and does occurs with both Wayland
and X11. I've a 4k display, and I tried already to change the scaling back to
100%, but this doesn't solve the issue.
Beware that this is a fresh KDE installation, no exotic widgets installed that
can mess the mouse pointer.
Notice that the Unreal Engine Editor works perfectly on the exact same
Machine/OS using Gnome.
STEPS TO REPRODUCE
1. Compile unreal engine
2. Open unreal engine editor
3. Open an asset in a new window
4. Try to hove something
OBSERVED RESULT
You will notice that you need to offset your cursor to properly hover that
menu.
EXPECTED RESULT
The button should highlight when the cursor texture is visually hover the
button.
