As described in https://github.com/prusa3d/PrusaSlicer/issues/6396

At startup, the 3D view is not rendered and the underlying background is left visible. The application remains responsive and can be closed normally. On the command line, it reports a series of

Ugly fix

Seems, it;s a bug of wxWidget 3.1.5? current head is already fixed. 
https://github.com/supermerill/SuperSlicer/issues/1093

I found only ugly hack which fixes the problem but I don't intend to suggest to commit.

BTW, the same problem there is in new 2.3.1 version of PrusaSlicer, which I suggested to commit ( https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=255363 )
Comment 2 Michael Reifenberger freebsd_committer freebsd_triage 2021-07-30 19:43:04 UTC 
The fix works for me too.
Even if the fix is quite ugly maybe it should get committed as a workaround
until upstream fixes the root cause.

The alternative is a non working prusa-slicer...
Comment 3 a.parseg 2021-08-02 17:53:54 UTC 
Works here too. 

Patched and locked waiting for a long-term fix.

Worked for me too.

We will remove the patch when upstream fixes the issue.

Thanks!
