Hi! Would it be possible for you to please provide a screen recording of this issue, so that folks could see the surrounding circumstances when this bug shows up? Thanks! Hey John, For sure! It must be that there is a small amount of mouse movement during the click, but it feels very wrong to me. I can't replicate if I pick my mouse up. Anyway, Here's a link https://www.dropbox.com/scl/fi/r21lxvz4tavrl5tj3cjc6/2025-01-13-21-31-30.mkv?rlkey=lq3dxwbh8s2wvqbg2d7vlz1zj&st=5bntrcpu&dl=0 That's a 118mb 1440p video so that the debug log is visible on each frame. Thanks, Kristian (In reply to littlegreendude55 from comment #3) > For sure! It must be that there is a small amount of mouse movement during > the click, but it feels very wrong to me.

I see how it's working on your system - and I can reproduce that an extremely small amount of mouse movement made while clicking causes acceleration, and that it does consistently stop if the mouse is picked up (so there's definitely no cursor movement). I retitled to the behavior that it seems we can both confirm, if that makes sense to you as well. This would be a usability benefit to look into, I believe, especially for folks who may have trouble clicking their pointing device without any motion. Thanks! |

Trying to do this on Okular can produce unexpected results. STEPS TO REPRODUCE 1. Open in continuous mode 2. Hold and drag to start scrolling the document 3. Click very quickly OBSERVED RESULT Document sometimes starts scrolling very rapidly EXPECTED RESULT Document should stop scrolling immediately.
