ADDITIONAL INFORMATION
Comment 1 fabrice salvaire 2025-12-04 18:29:04 UTC 
I can reproduce it using a normal session.

It happens at small zoom, text icons show artifacts (something like a wavy copy of a subpart of the frame buffer) until we move the mouse.
The zooming speed is irrelevant, only a small zoom matters.

Also, it looks like we need a debouncing, zoom event can be too fast for rendering.
