Bug ID: 464409
Summary: File selection dialog (KFileDialog?) list view shows
visual glitches when enabling preview panel
Classification: I don't know
Product: kde
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org
Reporter: andrea.i...@gmail.com
Target Milestone: ---
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.
Video is here (Google Photos still processing it to make it full-res):
