CID: 201404-14986 Dell Precision M2800

On this I+A (AMD/ATI Mars XTX [Radeon HD 8790M] [1002:6606]) system, the GStreamer autovideosink plugin does not work well with the proprietary fglrx driver (version 2:15.200-0ubuntu0.5)

Steps:
1. Install 14.04.3 + upgrade (3.19.0-30) + fglrx + Checkbox test suite
2. Run "gst-launch-1.0 videotestsrc ! videoconvert ! autovideosink"
3. Run "gst-launch-1.0 videotestsrc ! videoconvert ! ximagesink"

Expected result:
* A "Bar and static" video test screen will pop up.

Actual result:
* Only the command in step 3 will work, the command in step 2 does not, it will cause X to crash for sometimes, error log could be found:

Verified with the latest AMD driver(15.9, fglrx version: 15.201-0ubuntu1)[1], this issue does not exist with it.

As this issue will cause the camera display test and video test to crash (whitelist test cases), I will mark this bug as a blocker.

If the X didn't crash with the command in step 2, you will be able to see error message in the termnial:
X Error of failed request: BadAlloc (insufficient resources for operation)
  Major opcode of failed request: 151 (XVideo)
  Minor opcode of failed request: 19 ()
  Serial number of failed request: 51
  Current serial number in output stream: 52

And these issues only happen on discrete AMD GPU with fglrx, can't be reproduced on the Intel GPU.
