20799	Very slow to scroll geolocalized images	StephaneP	team	"==== What steps will reproduce the problem?
1. Load an image sequence
2. Keep pressing the next image shortcut
3. Compare scrolling speed between Josm latest and tested

==== What is the expected result?
Scrolling speed should be the same speed for both releases

==== What happens instead?
With the latest release, it's very slow. Perhaps it's related to #17072 or #20659 (no gamma/sharpness applied during the test)
See the attached video: At first I was using josm tested, then Josm latest.

==== Please provide any additional information below. Attach a screenshot if possible.
