[PB 6.03 Beta 10] [Kubuntu 23.10] Ctrl+Z slowdown with Wayland

When using Purebasic under Wayland undoing larger amounts of typing is very slow.
Purebasic uses XWayland in that case.

It seems the autocomplete window steals focus from the coding area.
A video can be seen here.
CTL+Z is hold down at 20 seconds. Ctrl+Y seems to be much less affected, but sometimes it is.
  • This slowdown does not appear under an X11 session.
  • When setting animation speed to "instant" in the KDE settings the autocomplete window can no longer be seen popping up, but the slowdown is still present.
  • When focus stealing prevention is set to extreme in KDE Settings slowdown does not occur, but autocomplete also does not work (Autocomplete key is inserted into source code instead)
  • GTK3 and GTK2 are affected.
  • Also happens with an old version of PureBasic (5.42 tested)
