Created attachment 126961 [details] Apitrace reproducing the issue With radeonsi, If primitive restart is enabled for two consecutive draws which use different primitive restart indices, then the first draw's primitive restart index is incorrectly used for the second draw. The attached apitrace reproduces the issue. The first and second draws should draw the same thing. The first is using a primitive restart index of 0xFFFFFFFF, and the second is using 0xFFFF (these are set using fixed index primitive restart and different index types).
