Viewer Scrolling Issue.
Ever since version 4.20 the mouse wheel scrolling on the viewer is not as responsive as it used to be, previously it would scroll the whole page with a single scroll click but now it takes 4 or 5. Has the scroll amount changed? Is there anywhere I can change it? Thanks.

Windows 10, Using 4.21 calibre. I tested with calibre portable and version 4.19 seems to be the last one without the issue. The issue is for page mode. Wil check the thread.

Having the same problem. Was not fixed in 4.22.
Works well using the 32 bit windows version though.
Any idea?

You need to go to Viewer Preferences --Scrolling behavior and set "Pixel scroll threshold:".

I found that setting it to 55 works for my system but you may have to use a different setting.

0 will work provided your mouse generates one scroll event per click, which i suspect most "traditional, low res" wheel mice do. The high res "precision" type and touchpads dont.
