That applet looks like its 8 years old?

Yes, I would be very suspicious of it. The backtrace is all in Qt and graphics code, so either the widget is doing something weird, or your graphics drivers are to blame here.

Regardless, I'm afraid Plasma is not supported on Kali Linux. Running everything as root is explicitly unsupported and never recommended, and will result in a million and a half other little weirdnesses, possibly including this one

If would like support from KDE for issues you encounter, I would encourage you to re-install your system with a more appropriate general-purpose Linux distro, such as one of the ones you can see at https://kde.org/distributions. If the issue still manifests after doing so, feel free to re-open this bug report.

Thanks for understanding!

Hi, thank you both for your responses;

Yes, this applet is very useful for modifying/activating/deactivating colorimetry on the fly.
To my knowledge, this is not possible with KDE's “night color” option.


Kali is equivalent to Debian Testing, with a freeze branch with 4 releases per year.
In this way, it is quite appropriate as an early distribution for reporting problems and preventing users of stable releases from encountering them one day...
KDE* packages are not modified by the distro, but I understand your suspicions.

In my opinion, running the whole system as root is more a problem of the security model than anything else; but this has *not* been the default on kali since 2020 (https://www.kali.org/blog/kali-default-non-root-user/); before that date you could always disable root and use a classic user (which is what I did for the 10 years before that). But once again I understand your arguments.

Anyway, after the June 2024.2 update (see version numbers above, KDE versions were incremented and NVIDIA proprietary drivers untouched), this problem seems to have disappeared for good. So...
