hi all...I'm on Fedora 32 and for every tutorial/sample I try to run with the runJvm target I just get a black window. thoughts on problem/fix?

I get this output too:
```VI: native@0x7f51284d2890

looks similar to <https://github.com/korlibs/korge/issues/174> but I'm running Korge 1.14.0

and...sometimes I get this

...setting `MESA_LOADER_DRIVER_OVERRIDE=i965` seems to fix the issue, similar to <https://bugs.archlinux.org/task/65580|this>. so I guess it's a mesa issue.

<https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/5838> might also be related. alright, so I'll just set that environment variable then. and maybe check back in a couple months to see if it's fixed.
