This sounds like a bug with QFileDialog itself, but I cannot reproduce it in other applications (checked with Konsole and KWrite). Reproducible: Always Steps to Reproduce: 1. Go to "Desktop Settings > Wallpaper". 2. "Open..." a new wallpaper (so that it is added to the selection), but while choosing an image, resize the file dialog. (It was too small for me initially, so I enlarged it.) 3. "Open..." the file dialog again. Actual Results: I'll attach an image of what I saw after step 3. Expected Results: In step 3, the file dialog should restore the size that I chose during step 2.
Created attachment 94410 [details] Wrongly rendered file dialog This is how the file dialog appeared after step 3. The window size is correctly restored, but the window contents don't fit into the window size. An easy workaround is to grab the resize handle at the bottom right corner of the window border. The next resize event fixes the rendering glitch and resizes the window contents to the proper size.
