SUMMARY
When the graphs are drawn on the System Monitor, random artifacts show up above
or on the graph drawing. It is most noticeable when "Fill opacity" is set to
"100%". The stray dots change each time the graph is redrawn. This creates an
ugly, distractiing effect.
It looks like a video bug, but it doesn't change when I move the window or
display it internal vs. external monitors. It may still be a low-level drawing
bug, but I haven't noticed the problem on any other apps.
I didn't see this problem in 5.27.x. It showed up when I upgraded to Plasma
6.0.0. I thought it was a Wayland bug at first, but I also see it on X11.
STEPS TO REPRODUCE
1. Open the History pane
2. Make sure CPU graph options have "Fill opacity: 100%"
3. See dots appear above the graph
OBSERVED RESULT
Graph has ugly dots around the edges. (See attached screenshot.)
EXPECTED RESULT
Pretty graph.
