Bugs item #1869877, was opened at 2008-01-12 02:40 Message generated for change (Tracker Item Submitted) made by Item Submitter You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105988&aid=1869877&group_id=5988 Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: GL Group: v3.0.0 Status: Open Resolution: None Priority: 5 Private: No Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: glColorPointer/ glVertexPointer broken Initial Comment: This might be related to bug 1067130, but I'm not sure, mark duplicate if needed. In the attached script, the polygon is often miscoloured, or lacks vertexes. If I disable GL_COLOR_ARRAY, vertexes draw fine. >From what I get it seems that calling glColorPointer overwrites some data in vertex pointer and/or vice versa. I get distorted views like http://img292.imageshack.us/img292/5295/bugwd1.jpg, while I should get the full polygon. If I change the order of functions artifacts change too and sometimes disappear, but nothing predictable. The similar program in C runs fine, so it is unlikely to be a driver issue.
