Using a GTK theme that utilizes the alpha channel crashes the hub.

To Reproduce
Steps to reproduce the behavior:

1. Install a transparent GTK theme(or create one)
2. Launch Unity Hub Native
3. Crash

Expected behavior
It should simply work, even if the app itself doesn't handle transparency properly, it should at least launch.

Please attach a debugger and provide the full stack trace of the crash.

gdb wasn't able to give me a lot of info:

Unhandled unknown exception; terminating the application.
[Inferior 1 (process 344144) exited with code 0377]
(gdb) bt
No stack.

Would you like me to try some other method?

You'll need to compile a debug build of UnityHubNative to get a stack from gdb.

I built in debug mode and it wasn't as useful as I'd hoped:

Unhandled unknown exception; terminating the application.

Made sure it's in debug mode and not stripped:

Probably not our bug then. You could consider reporting this to wxWidgets after confirming this reproduces in one of their test apps.
