+o Header file /usr/include/gl/feed.h is missing on VPro
systems. Bug Number 817635.

extension. Bug Number 821275.
+o Bias errors due to rounding get amplified by large
scale values. Bug 820752.
4.2 _B_u_g__F_i_x_e_s__B_e_t_w_e_e_n__I_R_I_X__6_._5_._1_2__a_n_d__6_._5_._1_1

+o Some triangles rendered incorrectly when
GL_VERTEX_PRECLIP is enabled. Bug Number 803888.

huge amounts of texture memory. It generally took
allocation of several hundred megabytes to cause these
problems. Bug Number 809118.
+o The query glGet(GL_STEREO) always returned GL_FALSE.
Bug Number 811510.
+o X Windows cursors larger than the supported 32x32 size

high when several thousand are in existence
simultaneously. Bug Number 814243.

sent to the VPro graphics hardware. This was most
often seen when User Clipping Planes were enabled, but
could also happen under other conditions. Bug Number
814449.
+o Texture max_lod state is sometimes corrupted when
switching between texture bindings and changing texture
minification filter. Bug Number 814554.
+o Pixels occasionally drawn incorrectly when using XOR
and INVERT operations in X11. Bug Number 814997.
+o Some combinations of glPixelZoom and glDrawPixels in
the stencil buffer can cause a segmentation fault
within the OpenGL libraries. Bug Number 816108.

through the hw to perform conversion from signed data
types to unsigned. Bug Number 804264.

Wrong scratchbuffer used in a couple of places. Bug
Number 804571.

were not being initialized fully in the HW Accum load
path. Bug Number 804575.
+o Tools like pixie and Purify which edit object code
interact badly with the fast-dispatch mechanism. Bug
Number 804578.
+o Octane2 V6 pipe hangs in fullscreen AA scene. In soft
accum code, doing an accumulate or load operation on
configs that require a gfx-to-gfx transfer for format
conversion, there's the potential for writing outside
the scratchbuffer bounds. Bug Number 805104.
+o In some applications which mix line loops and shaded
graphics, notably A|W Maya, timing problems caused the
rasterization hardware to hang. Bug Number 806456.
+o Deallocating shared graphics contexts could cause a
kernel PANIC. Bug Number 808361.
+o Use of proxy texture objects consumed texture memory.

documented. Bug Number 795885.

zero. Bug Number 797321.
+o glBitmap is affected by line and point fill modes. Bug
Number 797681.
+o 24bit scaling for Octane2 V12 convolutions needs
correction. Bug Number 799811.

after glPopAttrib(). Examples are the stencil
writemask, user clip planes, TexGen environments, etc.
Bug numbers 406391, 407193.
+o Incorrect handling of glCopyPixels() with convolution
enabled. In addition to possible pipe hangs the
determination of the ability to use optimized path
based on the values of the color matrix and color
buffer write mask was incorrect. The failure to select
an optimized paths had a very significant performance
implication. Bug numbers 365068 and 412633.

+o Incorrect handling of GL_FUNC_REVERSE_SUBTRACT_EXT
blend function. Bug number 370840.
+o Incorrect handling of OpenGL's 1D and 2D evaluators'
enable state. Bug number 357517.
+o Incorrect error detection and handling for a variety of
OpenGL commands both for illegal command parameter
values and for issuing commands that are not allowed
inside glBegin(...)/glEnd() while inside a
glBegin(...)/glEnd(). One of the problems that has
been fixed is described by bug number 372086.
+o glGetTexGen() of the eye or object plane equations
always returned the default values rather than the
actual equations set by the user (although these
equations were used when generating texture
coordinates). Bug number 407195.
+o glGetClipPlane() would return incorrect results when
more than 16 graphics contexts were running
simultaneously (the actual equations used by the system
were however correct). Bug number 421407.
+o Incorrect handling of linear fog; bug number 374451.
Note that there were two issues in this case. First,
there was a bug that caused certain fog parameters to
be corrupted; this has been fixed. Second, there was
no support for the IB2 chip, which has significantly
improved fog capability compared to the older IB1. In
order to preserve compatibility with previous releases,
IB2 capability is not enabled by default. One must set
the environment variable RE_FOG_MODE to the value 2 in
order to enable it. Note that IB2 capability must be
used if compatibility between RealityEngine and
InfiniteReality is desired.
+o There was a memory leak in glColorTableSGI() when
loading texture color lookup tables. Bug number
437745.
+o Iconifying and de-iconifying a running application
could cause a segmentation violation. The conditions
needed to cause this are exceedingly rare, except in
real-time applications running with non-degrading
priority. Bug number 452106.
+o Cursor colors with component values greater than 127
were handled incorrectly. (No associated bug number.)
- 16 -
+o Suspension and resumption of selection and feedback
modes were handled incorrectly. Bug number 458806.
+o A problem (introduced in patch 1442) with accidental
enabling of user clip planes was fixed. This bug was
manifest as incorrect feedback results after user clip
planes had been set. (No associated bug number.)
+o When using pixie with N32 OpenGL programs, the pixied
program dumps core. Bug number 372990.
+o Use of a glDrawPixels() command with an image of a
particular size could cause display-list corruption,
leading to a segmentation fault. Bug number 433594.
+o The change introduced in patch SG0001702 to fix bug
374451 accidentally created new problems with
exponential and EXP2 fog, for both OpenGL and IrisGL.
Bug number 467103.
+o The performance of IrisGL and OpenGL mode changes
(i.e., setting of the color mask, depth test, blending
and fog functions, enables, material binding, etc.),
and OpenGL matrix queries have been improved by more
than 30%.
+o OpenGL switching between different contexts
(glMakeCurrent/Read) performance has been improved by
about 25%.
+o The performance of OpenGL pushing and popping of the
current state (glPush/PopAttrib(GL_CURRENT_BIT)) has
been improved by a factor of more than 15.
+o The performance of OpenGL and IrisGL evaluators has
been improved by more than 40%.
+o glDrawPixels of small images (< 50K bytes) has been
tuned.
+o The size of the available graphics subsystem dynamic
memory (heap memory) has been doubled. Thus, for
example, OpenGL applications can use a larger number of
big pixel lookup tables (PixelMaps) simultaneously with
a large histogram.
+o The maximum width of an OpenGL viewport has been
increased from 2048 to 2560. Bug number 448477.
