Screenshot demonstrating visual glitches
I see the glitch during the animation going from large to small or small to large, but it always completes on my system. The end result looks as expected. A possibly relevant merge request was started @ https://invent.kde.org/system/dolphin/-/merge_requests/1073 Git commit 5ba28fbee04c0f2fa5b21cc2aa52eabc16e32f20 by Marco Martin. Committed on 23/10/2025 at 08:50. Pushed by mart into branch 'master'. Item view: don't do a zoom animation The zoom animation in all 3 views looks very glitchy, because icons that were already in view animate, those that weren't don't animate giving weird effect. In the list view mode, the tree view branches don't animate either, showing weird holes between the branches Also, while zooming in and out very quickly, is possible to have the selection rectangle somehow unsynced with the items sizes leading to visual glitches. Without an animation, zooming the view feels much faster and robust giving immediate feedback when zooming via ctrl+scroll or by dragging the slider around M +2 -23 src/kitemviews/kitemlistview.cpp https://invent.kde.org/system/dolphin/-/commit/5ba28fbee04c0f2fa5b21cc2aa52eabc16e32f20 |
Created attachment 185628 [details] Screenshot demonstrating visual glitches SUMMARY Rapidly scrolling in and out in the details view mode causes visual glitches - icons remain as their larger-size variants, selection/focus outlines might be retained at the wrong size, and the entry offset to the side. STEPS TO REPRODUCE 1. Switch to details view mode 2. Scroll in and out rapidly for a few seconds 3. Stop and observe (generally ending at the most zoomed out level)
