Created attachment 135797 [details] Screenshot of the media player applet SUMMARY Media player applet's headerbar contains a white line on top that starts from a few pixels from the left and extends all the way to the right. Also, the song's progress bar on the bottom seems to be "split in two" and have two different hues of blue on it. The first issue seems to be triggered by Xft.dpi=144 being set in ~/.Xresources, while the second seems to be consistent across systray applets even without this value set. STEPS TO REPRODUCE 1. Begin playing media from a media player so that the media player widget displays the media currently played in it 2. Open the media player applet from the system tray 3. OBSERVED RESULT There is a blue line over the top of the headerbar and the progress bar is split in two EXPECTED RESULT Widget headerbar has a fully solid gray background, the progress bar has a single hue of blue SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: 5.10.16-arch1-1, Arch Linux (available in About System) KDE Plasma Version: 5.21.0 KDE Frameworks Version: 5.79.0 Qt Version: 5.12.2 ADDITIONAL INFORMATION
Do other sliders in plasmashell (for example volume control) appear fine? Does this go away if you rm ~/.cache/plasma* ? and restart plasma?
I'm pretty sure this is a cache bug and would be interested to see if David's suggestion fixes it.

Re-opening because I found a way to reproduce this: 1. Use a 200% scale factor 2. Don't use Qt scaling (i.e. be on X11 and make sure PLASMA_USE_QT_SCALING=1 is not set) 3. Move your panel to a different screen edge 4. Open the System Tray 5 If it doesn't happen, move the panel to another screen edge again. Keep doing this until you see it. I can reproduce it on the first or second time. Deleting the Plasma SVG cache and restarting plasmashell fixes the issue.
