KWin Zoom is broken on multi-screen
SUMMARY
I have a multiscreen setup of two monitors: normally 4K vertical on the left,
and FullHD landscape on the right, both vertically centered, and global scale
is 100%. None of the relative position options matter, as I tested on various
combination and hit the bug nonetheless.
When I zoom in, the picture on both monitors is replaces with a zoomed &
stretches picture of the FullHD screen. Being streched to fill 4K+1K, it looks
really squashed. The mouse input is not redirected where you see it, but (from
what I can tell) at somewhat correct coordinates instead.
Zoom effect settings are as follow, none of them making any difference though:
Zoom Factor: 1.20
Mouse Pointer: Scale
Mouse Tracking: Push
Enable Focus Tracking: no
Enable Text Cursor Tracking: no
KScreen reports the following configuration:
