   Is there an existing issue for this?

   • I have searched the existing issues

   Changing tabs in the GUI will close and re-open the app, it also will reposition the app

   Expected behaviour

   Just switch tab

   Doing sudo apt install libxcb-cursor0 seems to have fixed the issue but also removed dark mode for me!

   Doing sudo apt install libxcb-cursor0 seems to have fixed the issue but also removed dark mode for me!

   What are the first 10 lines of your debug log file in both cases?

   Thanks, @benthecarman!

   From the provided logs, it appears that the reported bug occurs when building with the system’s Qt 6.4.2, rather than with the statically linked release binary.

   The requirement to install libxcb-cursor0 is already a known issue and is being tracked elsewhere.
