Sorry, but I do not known, why it appears. I only try to change wallpaper on second monitor by invoking special dialog using mouse. In next step, I cancel change.

Wallpaper does not change (indent), but ghost icons appear.

Nothing happens.

How bizarre. Do you by any chance have an NVIDIA GPU?

APU from AMD and dGPU from NVidia. I use Wayland session of Plasma6. APU is default one, I think.
Comment 4 Lach Sławomir 2024-02-15 13:02:10 UTC 
If this could be helpful. This happens on external screen. I am not very good in hardware standards, so I do not known if external screen is connected to APU or dGPU. I do not known, how mux working in my laptop. It is ASUS Zenbook Flip15.
Comment 5 Nate Graham 2024-02-15 16:07:52 UTC 
Thanks. Based on the described symptoms, I suspect this is a graphical glitch caused by issues with the NVIDIA drivers, but I have no proof. I'll leave this open for now.

Do the ghost icons go away if you move some window over it, or try to mark them with the mouse, to trigger a repaint of the affected area?
Comment 7 Lach Sławomir 2024-02-16 12:40:33 UTC 
Ghost icons does not go away, when moving window.
Comment 8 Zamundaaa 2024-02-16 14:09:08 UTC 
Okay, then this is relatively likely a bug in plasmashell, not in the driver
Comment 9 Nate Graham 2024-11-05 20:11:31 UTC 
Does this still happens in Plasma 6.2.0 or later? I recall this being a bug we fixed a while ago.
Comment 10 Lach Sławomir 2024-11-06 13:05:55 UTC 
Bug not appearing. Let's close this ticket. I will reopen it in future, If this bug appear again.
