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:
Copy code

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 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.
