Hi, I've just started experimenting with GEM. I compiled Gem and pd from source on Slackware 10.2 with kernel 2.6.13 and the nVidia binary driver.

The problem is that creating windows works just the first time. When I destroy it the window closes properly, but when I recreate it the windows remains black, and I get this infamous message in the log file:

NVRM: Xid: 6, PE0002 0470 c11daf4b 000bf858 00000000 00000003

I don't have any other problem using opengl on this setup, other than Gem.

Before digging into the code myself I thought to ask here. It seems that the code that disposes the window fails to free some resource.

Suggestions?

Thanks in advance, c.

I can't believe anybody else is having this problem. It hangs my machine if I mess in opening and closing Gem windows.

Anyway I solved it by adding:

glXMakeCurrent(info.dpy, None, NULL);

before calling glXDestroyContext in GemWinCreateXWin.cpp (line 240 in gem 0.90).

Now I can destroy and recreate windows without problems. Authors, please patch this.

from the source:

glXDestroyContext(info.dpy, info.context); // this crashes sometimes on my laptop

Hope this fix it. :-)
