I cannot reproduce it anymore after the change in 5.25.3. 
I don't know about Arch. Is the kde-plasmaaddons package also at the same version?

I don't know much about Arch, but is the package for kdeplasma-addons also updated to that version?  
I'd think so, but just to be sure
Comment 6 Patrick Silva 2022-07-12 21:09:11 UTC
kdeplasma-addons 5.25.3-1 package is installed. I can reproduce on Wayland and X11.
Comment 7 Chris Holland 2022-09-26 08:15:58 UTC
When Thumbnail Grid was written, this behavior was deliberate. It was so that when you have 6 windows open, and you close 1 window, it doesn't resize the window from 3x2 to 5x1. Also if you closed window #2 of 6, your mouse would be hovering window #3 letting you easily close that window as well.

https://github.com/Zren/kwin-tabbox-thumbnail_grid/pull/2

The Alt+Tab popup currently goes from 5x2 => 3x3 => 4x2 right now...

Since I have it available: In Windows 11, the rows do not repopulate if a window is closed after the Alt+Tab is show. In a 5x2, you can delete 4 windows from the first row, and it'll still contain 1 window on the first row (centered) and 5 windows on the bottom row. The windows in the top row do shift to keep them centered though, and the window can resize if you delete windows from both rows.
