Description Paul 2023-12-02 11:58:02 UTC 
SUMMARY
Attempting to use the network manager results in screen and panel corruption.

This is a rather elderly openSUSE Tumblweed machine. TW is normally kept up to date although the machine is only used as a "spare", I can't be precise as to when this issue first appeared.

This problem can be reproduced with a new user and the screen shots attached are those from a new, default, user.


STEPS TO REPRODUCE
1.  Launch Network Manager
2.  Select a network connection
3. 

OBSERVED RESULT
1. At initial launch all is OK: Screenshot 1
2. Network Manager and the Plasma Panel now become corrupt: Screenshot 2

EXPECTED RESULT
Normal operation...

I guess I must be the only one seeing this issue :(

Network Manager is the only Plasma Applet that triggers this screen/video corruption, I don't see the issue with, for example, Digital Clock / Calendar, Disks & Devices, Printers, Notifications, etc...

I appreciate I'm running Plasma on very elderly HW, but, I would like to resolve this issue if possible.

Thanks for the bug report, and I'm sorry nobody looked at it. This "black squares" issue is characteristic of graphical corruption caused by faulty graphics drivers. Is the "NV84" an NVIDIA G84 GPU from 2007?

And if you're still using the affected hardware with the latest supported NVIDIA drivers and Plasma 6.3.5 or later, can you mention whether the issue is still happening?

If it is, does the issue go away if you switch to the open-source Nouveau drivers?

Thanks again!

In the intervening year and a half since the initial report this hardware has now been retired... :)

OK thanks! Then probably there's nothing we can do to debug this, unfortunately.
