After ddc32537d6db69198e88ef0dfe19770bf9daa536 such applications as Chromium and Counter-Strike Global Offensive render a black screen, while Blender renders some gray rectangles.
Tested both with radeonsi and llvmpipe.
Thanks for reporting this.
FWIW we're also seeing confirm failures with this change (llvmpipe):
