SUMMARY I'm reproducing this with Firefox 108, but this issue has been annoying me for a while, so for sure it's reproducible on previous versions of both Firefox and KDE. STEPS TO REPRODUCE 1. Open Firefox 2. Open the Open file dialog (Ctrl + O) 3. Make sure it is using the KDE file picker instead of the GTK one 4. Disable the preview panel, then go to a folder with several files and hover your mouse over them - you shouldn't see any visual glitches 5. now enable the preview panel and repeat, you will see visual artifacts (line only half highlighted, contents not refreshing under cursor, etc). Artifacts can be so severe that you actually don't know anymore which file is selected, if it weren't for the text field just below. I have recorded this issue with OBS. When the glitch happens, at some point I stop moving the mouse and just try to navigate with arrow up/down. That's why you see the file names changing, but there is no visual hint at all about which file is currently selected in the list view.

Thanks for the screen recording! Does the same thing happen with the KDE file selection dialog from an app not using the XDG portal infrastructure? For example in a KDE app like KWrite that's been packaged by your distro, not a Flatpak or Snap app.

Thanks a lot!

FYI I just noticed on my system info that I have meanwhile updated to 5.102 (I update my Tumbleweed several times a week and the last update happened to happen tonight after I reported this). So I can confirm that this version is also affected, for what it's worth.
Thanks for the screen recording!
Spotted same issue on Firefox with Intel video card. Some info: --- Operating System: Fedora Linux 38 KDE Plasma Version: 5.27.7 KDE Frameworks Version: 5.108.0 Qt Version: 5.15.10 Kernel Version: 6.4.4-200.fc38.x86_64 (64-bit) Graphics Platform: Wayland Processors: 12 × 11th Gen Intel® Core™ i5-11600K @ 3.90GHz Memory: 31.1 ГиБ of RAM Graphics Processor: Mesa Intel® Graphics Manufacturer: Gigabyte Technology Co., Ltd.

Hello, are there any news about this? It's really a pain to do the simplest thing like picking a file to open with Kate, when you are in a directory with many files. It glitches immediately and you don't know whether the name displayed is the one of the item you have actually selected. This is a 15' bug IMO, it's a basic DE functionality and it's broken :( I'm attaching a screenshot of what it looks like. Thanks :)
Created attachment 162845 [details] screenshot of the problem in Kate file picker
Can no longer reproduce on Plasma 6.0.0, closing.
