Package: libgl1-mesa-dri
Version: 6.5.0.cvs.20060524-1
Severity: normal
I recently observed that spirographx from the rss-glx package was
emitting a lot of rows of hexadecimal byte triplets on stdout (not
even stderr), which I ultimately traced back to the following code in
Mesa's src/mesa/tnl/t_vb_render.c (lines 85-94), invoked when
rendering clipped lines:
#define RENDER_LINE( v1, v2 ) \
do { \
GLubyte c1 = mask[v1], c2 = mask[v2]; \
GLubyte ormask = c1|c2; \
printf("0x%x 0x%x 0x%x\n", c1, c2, CLIPMASK);\
if (!ormask) \
LineFunc( ctx, v1, v2 ); \
else if (!(c1 & c2 & CLIPMASK)) \
clip_line_4( ctx, v1, v2, ormask ); \
} while (0)
The fix should be pretty obvious. ;-)
For the record, I'm using the i915 driver, though the code in question
appears to be driver-independent.
