Yes, I understood -- but evidently, at least some places _had_ gotten the refcounting right (by locking the mutex before manipulating the count). Then there's my own https://bugs.freedesktop.org/show_bug.cgi?id=98602, about races on (seemingly) buffer object state. Come to think of it, I wonder if this is the same root cause as what makes CasparCG unusable on i965 (https://bugs.freedesktop.org/show_bug.cgi?id=91379). /* Steinar */ -- Homepage: https://www.sesse.net/ _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
