Attribute table pop-up moving on screen

[Gooseman2021]

Every time I add a new vector point to my layer the pop-up attribute screen opens (as it should). However, it moves vertically down the screen a little bit for every new point so after adding about 7 or 8 new points it has almost disappeared from the bottom of the screen.

This has only happened since the latest QGIS release 3.20.0

I think this is a Qt issue as I experience this annoying behavior since I switch to OsGeo4W testing/V2.

Thanks. Do I need to report this somewhere else? Or do you know if there is a fix for it. It is, as you say, really annoying.

Also happens with Identify tool.

If you don't close the opened dialog, next click will open a dialog at the same position.
If you close the opened dialog, next click will open a dialog slightly shifted in Y.

After a lot of opened windows:

Still valid on QGIS 3.22.3.

• Was still a valid bug in QGIS 3.24.0 w/ Qt 5.15.2 on Windows 10 20H2
• Is still a valid bug on fresh install of QGIS 3.28.0 w/ Qt 5.15.3 on Windows 11 22H2

It appears that Qt's pop-up QDialog that appears when completing digitizing of a new feature is "marching" down and to the right a few pixels on each instance. I searched the Qt Bug Reports but couldn't find an exact issue related to this problem.

Is this an upstream issue (a problem with Qt itself) or is this something that can be addressed on our end?

Calling restoreGeometry before the QDialog is actually shown have unexpected side-effects. What is happening is the widget is placed on the window as if it had no frame, then when the dialog is made visible (QDialog::show() is called) the frame kinda pops into existence, shifting the QDialog downwards (by the height of the windows titlebar) and slighlty rightwards (by some pixels, matching the border width of the window's frame).
#52472 delays the call to restoreGeometry until the dialog is actually shown, hopefuly fixint it without any side effects.
