test case

After updating Fedora from mesa-17.2.4 to 17.3.5 I noticed throughput in
XPutImage/XShmPutImage based workloads dropped significantly.

I'd noticed this before with a self-compiled version of mesa-18.0-rc, but
thought this had something to do with the chosen compile flags.

One test went from 40fps to 15fps (very small XPutImage requests immideatly
followed by XRenderComposite), while other degraded by about 30%.

System details:
* AMD Kaveri 7650k
* 4k + FullHD displays
* linux 4.15.3
* radeon kernel driver


How to test:
Run the attached java program and enable the "antialising" checkb=
ox:
java -jar JGears2.jar
