I need help solving a problem with Qt Creator. Qt Creator 10.0.1 is installed from the online Qt installer. I am using Ubuntu 23.04. When I creating a project and trying to change the mainwindow.ui file in Design Mode, I cannot place widgets.
For clarity, I recorded a video: https://drive.google.com/file/d/1qlzAaCi6uf5V8Z7dbBqdB2WHfTCVxtuK/view
I reinstalled Qt Creator, along with Qt Designer, and it still didn't give any results. If I use Qt Designer as a separate application, everything works as it should. Tell me what's wrong, thank you!
It seems like a known issue. Switching to Wayland solve the problem for me. See also this and this. Separate Qt Designer behaves exactly the same way in my case (didn't work on X11, works on Wayland).
