Created attachment 107587 [details] Taskbar screenshot with the glitches When the taskbar option "Show progress and status information in task buttons" is checked, wrong progress indicators are often displayed in taskbar entries after a file transfer with Dolphin. These glitches appear after the file transfer has ended, and remain visible until I close the window. I could reproduce this bug on an ArchLinux machine + another one with KDE Neon. See the screenshot in attachment.
Kai?

Haven't experienced that yet. In fact, I don't even get the badge with the number here :/

I made several file transfers to an USB drive with this option enabled, and I couldn't reproduce the issue. As soon as I disabled this option, the badges appeared on the wrong tasks again.
Something else: it seems to happen on the tasks that are on the left of the Dolphin tasks.
Can't reproduce in: Plasma: 5.12.2 Apps: 17.12.2 Frameworks: 5.43.0 Qt: 5.10.1 Kernel: 4.14.20-2-MANJARO OS: Netrunner Rolling
Me neither in Kubuntu 17.10 with Plasma 5.12.2, or Neon dev unstable. Yannick, if you can reproduce this with newer software, please re-open.
