Created attachment 180421 [details] Video showing the bug, all animations in kdeglobal/dolphinrc are disabled. STEPS TO REPRODUCE 1. Open Dolphin. 2. Ensure the Information Panel is visible (View -> Panels -> Information Panel or F11). 3. Ensure previews (e.g., for images) are enabled in the Information Panel settings. 4. Select a file with a preview (e.g., a landscape image). Observe the preview in the panel. 5. Immediately select another file with a preview that has a significantly different aspect ratio (e.g., a portrait image or a square one). OBSERVED RESULT The preview image widget in the Information Panel visibly and rapidly scales/resizes from the previous preview's dimensions/aspect ratio to the new one's. This creates a jarring visual "jump", "jitter" or animation effect that is independent of the global KDE/Qt animation settings. EXPECTED RESULT Ideally, the new preview image should appear instantly without any visible scaling animation or transition from the previous preview's dimensions. Alternatively, there should be a setting to disable this specific scaling effect, or it should respect the global `AnimationsEnabled=false` / `AnimationDurationFactor=0.0` settings in `kdeglobals`. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux (Using Cinnamon DE, not Plasma) Qt Version: qt6-base 6.9.0-1 ADDITIONAL INFORMATION - Standard methods to disable animations (`AnimationsEnabled=false`, `AnimationDurationFactor=0.0` in `~/.config/kdeglobals`) have been tried and do *not* affect this specific preview scaling behavior in the information panel. - Attempting to set `AnimationDurationFactor=0` within the `[KDE]` section of `~/.config/dolphinrc` also had no effect on this behavior. - The effect is visually distracting and uncomfortable, especially when browsing quickly through many files (like photos) with varying aspect ratios. - Using Arch Linux with Cinnamon DE, Dolphin installed from official Arch repositories. Windowing system is X11.
