I can't reproduce any issue here. When I rename a tag via properties in the left sidebar, there is no visible refresh of the thumbnail view. The changed tag name appears immediately under the thumbnails.
Which database are they using exactly? We may need a screencast.

Please test whether the problem also occurs with this version:

https://download.kde.org/stable/digikam/8.2.0/digiKam-8.2.0-Qt5-Win64.exe

Here's the screencast requested. The screen response was a bit slower than usual probably due to the screen capture app. For info the database used is MariaDB. The digikam version is digiKam-8.3.0-20231213T161333-Win64.exe.

This is definitely a graphics card driver problem, as well as your problem with the face shifting. We also know this from Qt5. So it seems to still exist with Qt6. I have to look for the old bug reports. The problem occurs if you have 2 graphics cards in the system and have set another graphics card as the accelerator that the graphics output to the monitor.

To update, the app is running on an Intel i5 11th generation notebook with no external monitor and using Intel built in graphic engine.

I downgraded the app to ver. 8.2, specifically digiKam-8.2.0-20231116T055817-Win64.exe and have no issue with the renaming. The thumbnails stayed in place without going blank.
