Bug - Trails appear when dragging objects around

[PowerUser64]

Testing out the newest release, I noticed there are some strange artifacts that appear when dragging things around (selections and clients). Here's a screen recording of it:

raysession.webm

It's purely graphical, and it goes away when the view scrolls at all, so it's not the biggest deal, although it is a little distracting.

Thanks for the report. Of course I can't reproduce this issue. What is your distribution and your Qt version (help -> about Qt will give you the Qt version) ?

[PowerUser64]

Thanks for your quick response! I'm using Qt v6.10.0, and I'm on Endeavour OS. Let me know if you need anything else!

Ok. I reproduce partially it in a VM. I have troubles only if the movement is not integrally in the scene.
You can see the scene size if in preferences dialog, in the "Theme" tab, you set "Grid" to something else than None.

Certainly something due to Qt6.10, Manjaro (with Qt6.9) is not affected. They certainly changed something in the QGraphicsScene updates or optimizations. It will certainly be quite boring to fix...

Because Qt6.10.0 is very recent, I prefer to wait and see if the problem will be fixed in Qt6.10.1. Fix this kind of bugs can be time consumptive.
