Description spamless.9v5xj 2022-01-24 05:44:59 UTC 
Created attachment 145832 [details]
Two icons for Chrome can be seen

SUMMARY
If Google Chrome has flags enabled, the Icons-Only Task Manager will sometimes not properly group the application, as the flags cause Plasma to believe it is a separate program

STEPS TO REPRODUCE
Unfortunately the exact trigger for the bug is unknown, though I have noticed it arising from running Google Chrome with various flags enabled using an auxiliary chrome-flags.conf placed at ~/.config .

OBSERVED RESULT
Two copies of Google Chrome are created in the taskbar

EXPECTED RESULT
The Google Chrome icon combines properly

SOFTWARE/OS VERSIONS

Linux/KDE Plasma: 
(available in About System)
KDE Plasma Version: 5.23.4
KDE Frameworks Version: 5.8.0
Qt Version: 5.15.2

ADDITIONAL INFORMATION

Relevant line in the file plasma-org.kde.plasma.desktop--appletsrc :

launchers=applications:google-chrome.desktop,applications:google-chrome --enable-features=VaapiVideoDecoder --use-gl=desktop.desktop,applications:steam.desktop,applications:signal-desktop.desktop,preferred://filemanager,applications:org.kde.konsole.desktop

(Normally the second icon appears unpinned and will not be in this file; in order to investigate this bug I manually pinned the duplicate which led me to discover this anomaly)

Contents of ~/.config/chrome-flags.conf :

--ignore-gpu-blocklist
--enable-gpu-rasterization
--enable-zero-copy
--enable-features=VaapiVideoDecoder
--use-gl=desktop

Is that on X11 or Wayland?
Comment 3 Nicolas Fella 2022-01-25 00:43:39 UTC 
Can you please hover over the second entry and make a screenshot of the popup?

As noted before the bug happens randomly, but I'll grab a screenshot once it occurs.

Although for the record, visually on the end user side there was nothing out of the ordinary; the popup simply showed thumbnails just like any other icon.
