Thanks for the report! It would help to have more precise steps-to-reproduce (click here, then click here, etc) as I don't know how your webapp works. Maybe you can attach pictures you used for testing to this bug, or upload them somewhere?
Jan, step 1) click and load (or drop) in the box for "source image" any image you like step 2) click and load (or drop) in the box for "target image" any image you like test 1: scroll the mouse-wheel while cursor is over the "target image", and watch in the FPS in the debugger. Example of that is attached - comparing FPS shown in the debuggers in Firefox and Chrome performing the same action. After you have loaded (any) 2 images, as source and target: test 2: press "download" from the "target image" box. Compare the performance (the time it takes to render full size) of Firefox vs Chrome/Vivaldi/Opera. Try using larger than 20MP image, as the larger the image, the more noticeable the performance difference is. If you need to find a large size images for the test, you can use google. Here are some over 20MP: https://www.google.com/search?q=color+calibration&source=lnms&tbm=isch&sa=X&ved=0ahUKEwidkJPS_vzTAhWCFZoKHYutBkcQ_AUICigB&biw=1536&bih=769&gws_rd=cr&ei=nW8fWazjHeSV6ASh0AI#q=color+calibration&tbs=imgo:1,isz:lt,islt:20mp&tbm=isch
Seems like a nested-function was killing the performance (compared to Chrome). After removing it, performance is decent.
