Hello,
with previous versions of Krita, I used to hide Docker Titlebars because I find it useless since we have the corresponding tab names.
The manipulation was to add in kritarc file
LockAllDockerPanels=true
(source : https://www.reddit.com/r/krita/comments ... r/e36ws3u/)

But it doesn't work anymore.
Is there an option or manipulation to permit to hide Docker Titlebars again (as shown in joined pictures) ?

I just tested it, and it works fine for me. Make sure it's in the unnamed section at the top of the kritarc file.

Thank you for the quick answer, as usual.

For me, the trick only hide the close and minimize buttons, not the title. So the height of the Docker stay the same.
See following picture :

Any idea ?
Maybe it is a KDE System config ?

Ah, now I see what you mean. The options till locks, but I guess the people at Qt changed the way dockWidget->titleBarWidget()->setVisible(false); works... (It's in Qt, not frameworks, the breeze widget style or Krita, because the fusion style does this too.)

I don't think we can do a lot about that, but it's pretty weird. If you make a bug report I'll dig in a bit and try to find what changed.

OK,
