At seemingly random times, the Comics plasmoid tries to refresh the comics and get caught in some kind of loop (blue loading "wheel" never stops, see screenshot) causing plasmashell and X11 eating up much of the CPU. Reproducible: Always Steps to Reproduce: 1. Add Comics plasmoid to plasmashell and a few comics (I have "Calvin and Hobbes", "PhD comics" and "XKCD", maybe "Calvin and Hobbes" is trigging the bug) 2. Wait for the plasmoid to try to refresh the comics 3. Comics plasmoid is endlessly loading and plasmashell starts using a lot of CPU Actual Results: Plasmashell is using a lot of CPU. Expected Results: Comics refreshing should stop and CPU usage should be very limited.

Update the version to 5.7.1 : no change in behaviour.

Not fixed in 5.9.0.
Yes, I can confirm (openSUSE Tumbleweed, Plasma 5.9, KF 5.30). So not a duplicate from the solved bug above.
Seems to be fixed with Plasma 5.10 and Qt 5.9. Lucas Weiss, can you confirm?
I added the applet back on my desktop and will report in a few days if I have noticed anything.
Hi Can confirm that it is not fixed. Plasma 5.10.2 and Qt 5.9 on KDE Neon packages. It is difficult to reproduce though as it happens at unforseen time intervals, from half an hour to several hours. But when it happens it stays there for any period of time. One has to change the Comic tab to stop it or restart plasma. I can provide an strace/ltrace or other means of debug info next time it happens if that helps.
I'm not sure whether or not this will actually help anyone but I am having the exact same issue as described in the original report in that a presumably stuck refresh of comics causes high cpu usage by plasmashell. I have one new note to make thanks to the fact I am usually offline. The problem will only occur when there is an internet connection. I am always connected to a lan without any dns and the problem does not arise until I connect to web via second network. OS archlinux, kernel 4.17.12-arch1-1-ARCH Software Versions: Plasma 5.13.4 Frameworks 5.48.0 Qt 5.11.1

Looking at old bug reports: this is now fixed. Closing.
