Description PK 2021-11-27 07:07:59 UTC

When I use the perspective-tool in Showfoto (7.3) the "handles" don't follow my movements when I'm using Wayland. Under X it's like a well oiled machine. 


STEPS TO REPRODUCE
1. start up the perspective-tool in digikam/showfoto
2. grab a corner and try to drag it

OBSERVED RESULT
Under Wayland the handle follows my movement in a choppy unpractical way, under X it directly follows my movements.

EXPECTED RESULT
That I can freely move the corners of the perspective-field

I tested it here under a Plasma Wayland session on openSUSE Tumbleweed. The problem is a performance problem when copying the image data. The same problem exists in the text tool that moving the text box over the image is extremely slow.

@PK,

What's about this file using current 8.2.0 AppImage Linux bundle ? It's
reproducible ?

Thanks in advance
