The nexuiz and xonotic games display abnormally. Bisect shows: 62b971673950148eb949ba23d7fdc47debea16f0 is first bad commit. I am investigating this issue and trying to figure out wtf is going on and why gallium drivers don't have this issue while using exactly the same code. I will revert the commit if I don't find a fix soon. It fixed with commit 9f0f2f9512c3c9dcf875efa490b587f010b260c1. Verified. Fixed with commit 9f0f2f9512c3c9dcf875efa490b587f010b260c1. |
