Seems, it;s a bug of wxWidget 3.1.5? current head is already fixed.
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 )
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...
Works here too.
Patched and locked waiting for a long-term fix.

We will remove the patch when upstream fixes the issue.
