Apitrace of dolphin

Dolphin emulator's GPU texture decoder is now supported, as it requires compute
shaders. It however misrender and the line 
"The kernel rejected CS, see dmesg for more information"
is repetitively printed.

I have the folowwing lines repeated in dmesg:
"[ 4885.617750] [drm:radeon_cs_ioctl [radeon]] *ERROR* Invalid command stream !
[ 4885.624044] radeon 0000:01:00.0: evergreen_cs_track_check:982 mask
0x000000FF | 0x000000FF no cb for 1
[ 4885.624047] radeon 0000:01:00.0: evergreen_packet3_check:1908 invalid cmd
stream"

I have attached an apitrace of dolphin. The trace renders fine on Skylake. It
seems that the first rejected CS is at frame 0, call 2731.

Tested on HD 5770.
