Hallo!
I'm experiencing a similar behaviour
good to hear that I'm not alone ... ;)
but I can't display anything in the gem window, neither 2d or 3d
have you tried text2d (that's the only thing that worked for me normal ATM ... but I haven't tried that much)
window updates its content but nothing is displayed at all. And I can't destroy the gem window.
I can destroy the gem win ...
Has anyone some hints how I could try to debug that issue ?
Thanks, LG Georg
