Description Rainer Finke 2020-12-08 11:35:20 UTC 
When using the zoom slider on the bottom right in Gwenview 20.11.90 on Wayland, the zoom is often delayed and really sluggish. If I use the mouse wheel (enabled in settings) to zoom, it works almost instant.

STEPS TO REPRODUCE
1. Open picture in Gwenview
2. Zoom with slider

OBSERVED RESULT
Zoom is slow

EXPECTED RESULT
Zoom works instantly and fast
