Created attachment 147242 [details] GIF where I scroll by the same amount, a single "click" on both the file browser and the icon browser SUMMARY With a high-resolution scroll wheel, such as the one found on the MX Master 3 mouse, scrolling in the file icon picker is insanely fast. I believe that's because that specific window has no support for high-resolution scrolling, but is still using each high-resolution scroll step as one entire low-resolution step. There are several high-resolution steps per low-resolution step, IIRC something like 8, so scrolling on that window is roughly 8x faster than it should be. On the normal file manager, scrolling is at a normal speed, and it does seem to support high-resolution scrolling. On the GIF, every time I scrolled, it was only a single step. You can notice that on the normal file manager, it scrolls a normal amount, but on the icon picker, it scrolls a lot more. STEPS TO REPRODUCE 1. Have a high-resolution scrolling device (MX Master 3 in my case) 2. Go to the file manager, on a folder that requires scrolling 3. Scroll by a single "click" on the mouse wheel 4. Notice scrolling is at a normal speed 5. Go to the icon picker for a file or folder 6. Scroll the icons by the same amount as before, a single "click" 7. Notice that it now scrolls a whole lot more, at an insanely fast speed OBSERVED RESULT It scrolls a lot more, and a lot faster, on the icon picker. EXPECTED RESULT It should scroll by the same amount, and at the same speed, on all scrollable elements. High-resolution scrolling should be properly supported on all elements.

This doesn't solve your specific issue, but in addition to what you are asking, I am thinking that there should be a scroll wheel sensitivity slider in the System Settings -> Input Devices -> Mouse, just as there is a Pointer speed slider.

Agreed! Also, being able to disable high-resolution scrolling on the mouse settings would also be great.
