Summary If the user changes the preferred icon size and then resets the zoom level, it always returns to the default size. How to reproduce 1. Go to "Configure Dolphin" > "View" > one of the mode tabs (Icons/Compact/Details), or modify ~/.config/dolphinrc directly. 2. Set both default and preview icon sizes to a different value (such as 64 pixels for demonstration). Hit "Apply". 3. Restart Dolphin (not needed, just to rule out loading issues). 4. Make sure the relevant mode is selected: "View" > "Change View Mode". 5. Hit Ctrl++ a few times. 6. Select "View" > "Reset Zoom Level", or hit Ctrl+0. Expected result The icon size should return to 64 pixels or whatever else the user prefers. Observed result The icon size changes to the default size, e.g. 32 pixels in Icons mode.
