that's expected (and desired) behaviour.

glxinfo is attached.

thanks. so you are using nvidia proprietary drivers. which driver version, which card=

there is also [gemglutwindow] it seem to do the same thing, but I've no clue about how it works

what's "the same thing"?

[gemglutwindow] gives you glut, so you can have ugly menus in the window... [gemglxwindow] gives you glx, which might give you context sharing...

i forgot: [gemglutwindow] will work on all platforms (that support glut, which are all that i currently care for), whereas [gemglxwindow] will only work on X. all of these [gem*window] externals provide a common interface, but might have additional features.

I'm trying right now to reproduce the crash, but it only happens with [gemglutwindow], when [destroy( is sent

Program received signal SIGSEGV, Segmentation fault. 0x00007ffff61f9170 in gem::Context::push() () from /usr/lib/pd/extra/Gem/Gem.pd_linux

interesting. could you get a full backtrace?

in any case, multiple-windows are still quite experimental (they are default in the dev-version, in order to get feedback like this)
