Hi. We are seeing a leak of things created in XMesaCreateVisual, as
called from fakeglx.c. I don’t see anywhere that XMesaDestroyVisual is
called. I see a free() in destroy_visuals_on_display, but I don’t know
how often that is called. Are these visuals intended to be kept around?
The visual is allocated in XMesaCreateVisual, from save_glx_visual,
from choose_visual, from Fake_glXChooseFBConfig.
It may be that the problem is that I’m not finding and reusing one in
the list, but separate from that, I am curious why XMesaDestroyVisual
isn’t called.
Any thoughts?
There's no GLX function for explicitly destroying a visual so that's
why XMesaDestroyVisual() isn't called. Instead, we register an X
display callback that's called when the X Display is closed which
frees visuals and other things.
So, when you call XCloseDisplay, they should get freed.
