Looks like a cache problem, have you cleared ~/.cache/plasma* files? Do you have screen scaling enabled? (In reply to Kai Uwe Broulik from comment #1) > Looks like a cache problem, have you cleared ~/.cache/plasma* files? Do you > have screen scaling enabled? No scaling enabled. Tried clearing cache, logged out and back in, the problem still persists. Additionally, the "sliced" appearance is much more rare and I still couldn't figure out what causes it. I can easily confirm that it alternates between flat and rounded states just by raising the lowering the volume repeatedly using my keyboard's volume keys. Now that I've seen this, I can't un-see it. :( I've looked into what could be causing this. How to reproduce and test changes: you need to log out and in again because restarting plasmashell makes the bug go away What's not causing it: the PlasmaComponents qml files themselves, both PC2 and PC3 The culprit is most likely frameSvgItem. If you replace it with a circular Rectangle as the indicator you'll see this bug doesn't happen. See attached hack. It shouldn't be a problem with our SVGs since I've seen it happen with other themes but can't say for sure. Created attachment 128816 [details]
A naughty hack that makes the bug go away
Thanks, that looks like a good avenue of investigation. Actually (and fortunately) it might just be an SVG problem. Gonna attach an SVG from the Matcha-Color theme that doesn't have this issue. Noah, do you have an idea what we're doing wrong and they're doing right? Created attachment 128820 [details]
Bug-free 'bar_meter_horizontal' SVG
from the Matcha-Color theme
i do have the issue sometimes, tough also can't much understand. bar_meter_horizontal looks very simple so shouldn't do it *** Bug 424614 has been marked as a duplicate of this bug. *** fixed in plasma6 |

Change volume so that the volume indicator appears OBSERVED RESULT The volume bar on the indicator will have an inconsistent appearance. EXPECTED RESULT It's look should not change.
