--- Comment #27 from Dan Sebald <daniel.seb...@ieee.org> --- Created attachment 114592 --> https://bugs.freedesktop.org/attachment.cgi?id=114592&action=edit swrast legacy Piglit test images SWRAST_DRI.SO LEGACY This is the current repository version of the legacy swrast driver. The first image (upper left corner) shows the original problem I and others had experienced: vertical lines due to dropped pixels associated with GL_MAX_TEXTURE_SIZE transition. Interestingly, this doesn't happen when xfactor is negative (one of the "pass" tests). The Y-direction exhibits a good gradient ramp, except for the very last pixel in the positive direction, which is missing (look for the dark line near the top of the window), so this test fails for reasons different than in the X direction. The positive over/underrun with magnification X test actually looks good, and I don't know why the test is failing. These things can be looked at in greater detail later. The other three over/underrun tests in the X direction clearly show that glDrawPixels isn't zooming to the right scale. This is the other potential bug I've wondered about. -- You are receiving this mail because: You are the QA Contact for the bug. You are the assignee for the bug.
