broken rendering after having switched between view modes

SUMMARY
In some cases, both the dolphin application and the dolphin file picker called from other applications (e.g. to upload files from firefox) stops rendering the file list correctly, only refreshing a small portion of the screen when scrolling, changing location etc.

STEPS TO REPRODUCE
I haven’t managed to find a 100% reliable way of reproducing this yet. It definitely happens most often in file pickers called from Firefox, but I have seen it in the standalone Dolphin app too.

In some cases it seems to be folder-specific, where one folder will work file, then I move to a folder which triggers the bug (often my Downloads folder), and from then on the UI is broken.

Resizing the window causes a full-window refresh, but rendering is broken again as soon as I scroll.

The rendering issue happens in all view modes, and, once triggered, persists when switching view modes.

OBSERVED RESULT
Broken rendering

EXPECTED RESULT
Normal rendering
