Comment 1 Jason Ekstrand 2014-09-30 21:41:59 UTC 
How about latest master?  There were some bugs in the first push that I fixed a couple hours later.
Comment 2 Ian Romanick 2014-09-30 22:19:49 UTC 
I was testing on 408aa46c.  There are a couple commits since then on master, but both are in the freedreno driver.  Re-testing at cc355f1c had no change.
Comment 3 Jason Ekstrand 2014-10-01 00:50:37 UTC 
I think I found the bug and sent a patch to the list that should fix it.  Let me know if it does.
Comment 4 lu hua 2014-10-08 03:03:32 UTC 
I can reproduce it on (master)16b53005a7df4249fecb6641af0934c32181fdea

Perhaps fixed now?

Works here.
