Description kaminata 2025-10-13 15:22:09 UTC
SUMMARY
Hello,
after recent update, windows and dialogs doesn't remember their positions. For example if you take a screenshot, Spectacle open itself on the upper left corner. The same applies to the credentials dialog, rename dialog, copying dialog if it's enabled, properties dialog for file/folder, etc. And since you can set a rule for some windows, for others you can't for they are combined in a way. It's a 15 minutes bug for me. It's one of the first things I notice in any DE.

STEPS TO REPRODUCE
1. Start spectacle or trigger a dialog window.
2. 
3. 

OBSERVED RESULT
The items doesn't remember their last positions.

EXPECTED RESULT
The items should remember their last positions.

This problem is not lik in the oher theme. I'm using KDE for more than 13 years and yesterday the problem appeared for the first time. It's a result of an update. It's not some 25 year old bug. It's a regression. I hae a bakup which is a month old. I restored my system from it and here's not a problem at all. I ugraded and it appeared again. It's from some recent update. And I'm on X11, not Wayland.

And one more thing - I'm don't using activities at all. I there's no need to restart, the problem is always there - no restart or logout ar needed.

You probably changed the placement of new windows to always open in the upper left corner.

Window Managment > Window Behavior > Advanced

But you're right, it's a completely different bug. It seems this setting isn't working anymore and it's being ignored. I'll edit the bug's title.
Thank you!

IIRC this is a Qt 6.10 on X11 bug. Am I recalling that correctly, Nico?
Comment 8 Nicolas Fella 2025-10-14 15:45:16 UTC
uh, not that I'm aware of

I think you're right for it appeared this days and Qt 6.10 was released recently.
Comment 10 kaminata 2025-10-14 16:33:13 UTC
I tried to downgrade Qt to 9.x.x but KDE won't start after a reboot. If you can tell me which packages I have to downgrade along with Qt so I can boot after that, I'm ready to try.

Some additional info - I just realized none of the 5 options (Minimal Overlapping, Maximized, Random, Centered,  In Top-Left Corner and Under mouse) are working and are ignored completely.
