Created attachment 136669 [details] Missing delegats Can also result in delegates missing from the grid
I've tried to reproduce this issue but I'm unable to. I have 42 wallpapers listed and no amount of resizing makes them vanish or gather together like yours have. Is this reproducible on your system?
Yes, I can still reproduce it. Do you have wallpapers with long strings whose names get elided?
Cannot reproduce with several hundred wallpapers, at least a few of which have elided titles. It looks like the font size is different between those two screenshots. Could that be a clue?
Created attachment 136720 [details] Video of the bug I don't know but here's a recording of the bug. (not related to theming either, I checked with stock settings)
Thanks for the video. I just got it to happen by resizing the window violently a lot. :) I can't figure out what action or movement makes it happen, but I can confirm the issue now. I cannot reproduce it with any System Settings KCMs using grid views when I open them up in KCMshell and try the same violent resizing. Can you?

Can you? Yeah it does take some violence to trigger :) Can't confirm with KCMs either. And what's really interesting is that I can't reproduce the bug on a different machine with the same software versions, but with Nvidia proprietary drivers. (I'm seeing the bug on an Intel iGPU machine)
iGPU for me too, though I'm not sure that could be related.
(In reply to Nate Graham from comment #8) > iGPU for me too, though I'm not sure that could be related. I think it might be driver related as I'm on NVIDIA proprietary drivers and can't replicate it. They do overlap but only for a few milliseconds until it sorts them properly.
It can't be a driver bug because the items aren't just painted in the wrong place; they're physically (well, virtually) located there too, with their mouse handling offset as well. That suggests that the issue is above the driver layer.
Can confirm in the settings window for the Notes widget, which has a grid view in it.
