Created attachment 136712 [details] Weird horizontal lines in charts See attached image for more info.
I've just tested this on git master and I'm unable to reproduce the issue.
What kind of GPU are you using? It happens on my Intel iGPU so guessing it's a driver/hardware issue
(In reply to David Redondo from comment #2) > What kind of GPU are you using? It happens on my Intel iGPU so guessing it's > a driver/hardware issue Me too, I use intel integrated graphics and modesetting driver. But KSysGuard charts and network/disk activity/cpu widgets and gnome disk benchmark and do not have this problem at all on same machine. Even some heavy JavaFX and Swing apps that display charts do not suffer from this problem.
This also happens on 5.81.0
Cannot reproduce on current git master. I vaguely recall a thing to fix this recently. Can you reproduce the issue in Frameworks 5.82, or even better, current git master?
With 5.82.0 the problem is still persistent.
This is a driver bug in the intel driver. One that may be fixed in a more recent version of the driver if I am understanding this correctly.

No, all other apps that have charts are not suffering from this problem, only the new monitor app is affected, so I don't think it's driver bug.
Just to be sure, are you using HiDPI scaling? (especially fractional scaling).

Git commit 3e2b4d1d5114b685e958cac3d5d511cf68718a02 by Arjen Hiemstra. Committed on 23/02/2024 at 12:10. Pushed by ahiemstra into branch 'master'. linechart: Use fwidth of the point instead of sdf to avoid conditional fwidth Apparently fwidth in conditional contexts can cause glitches, so use fwidth() of the point instead as that is not conditional.
