DG965RY Intel motherboard with VGA connector connected to an LCD
(The above turns on Xrandr support in the SDL, because xvidmode was removed)
And start an SDL application, it freezes.
I attack backtrace of etracer and compiz.
Note that compiz hangs in same way, and always.
The interesting part of the backtrace is:
#5 0xb7565a30 in DRI2GetBuffersWithFormat (dpy=0x86bda50, drawable=97, width=0x882e47c, height=0x882e480, attachments=0xbff6e69c, count=2,
outCount=0xbff6e6c8) at dri2.c:428
#6 0xb7563f62 in dri2GetBuffersWithFormat (driDrawable=0x882e458, width=0x882e47c, height=0x882e480, attachments=0xbff6e69c, count=2, out_count=0xbff6e6c8,
loaderPrivate=0x882e3b8) at dri2_glx.c:435
#7 0xb6f6cbf3 in intel_update_renderbuffers (context=0x883dcd8, drawable=0x882e458) at intel_context.c:253
Note that older mesa, 465fee75ee8991349da742e5a1a5be3cd179bb62 doesn't have that problem. Maybe I should do an bisect.
