How to reproduce

QubesOS is a Linux system that runs Applications inside isolated VMs running common distributions such as Debian or Fedora so e.g. you can use potentially insecure software like the Bambu network plug in with reduced risk that data in your other applications is being stolen or corrupted.

For some reason all the dropdowns in Orca instantly close, I speculate its due to an interaction with focus management/pointer security in Qubes (e.g. preventing one app from spying on the pointer position in other apps).

To reproduce:

1. Run Qubes
2. Create Debian 12 app image, start the Orcaslicer app (I've tested 2.2.0 and 2.3.0 as well as older versions in fedora compiled from source) and go through the ordinary startup (In my case configured for X1C, but the choices don't matter).
3. Open the prepare tab
4. Click on any dropdown such as nozzle selection, bed type, filament type, seam position, etc.

Actual results

Observe that its impossible to select anything because the dropdown flashes and instantly vanishes. It doesn't appear to be possible to work around with key presses.

Expected results

It should be possible to make a selection.

While fault might arguably lay with Qubes here, I can't find evidence of any other program (other than Bambuslicer) exhibiting the same failure... so it seems like Orca is doing something unusual if not technically wrong.

Project file & Debug log uploads

Nothing obvious in the logs, issue happens with any project including an empty one.

Anything else?

See also: #3881 (which I fear may not have recieved any attention because it was opened as a discussion rather than an issue).

I'm happy to make videos, run tests, etc... though the behavior is 100% reproducible, I understand someone might want to give something a try without going through the effort to run qubes. :)
