When scrolling or resizing grahics (photos) Firefox is reacting very slowly - takes seconds per move or zoom. Seems like slowness started after 13th of March when version 86.01 was installed. I have tried deactivating Graphics Processor (no improvement) then re-activating (still slow) then changing number of GPUs to use (still slow). Chrome show no slowness on the same sites. This page is an example - when zooming in to read handwriting. https://www.sa.dk/ao-soegesider/da/billedviser?bsid=181415#181415,30802573 Viewing maps like Google Maps causes no slowness.
