I am rotating an Image through a BufferStrategy created out of a Canvas. The front and back buffers are accelerated and FlipContents is set to BACKGROUND. Till jdk6u10-b11, the background of the application was appearing black but on 6u10-b12 PIT build, the background appears in white color. Other FlipContents types seem to work fine.

I reproduced it on WinXP with Nvidia GeForce 7600 GS, installed with the latest driver using jdk6u10-b12 PIT build. The background becomes black when I turn off the D3D on 6u10-b12.

I have attached a sample test herewith. Just compile and run the test. If you see a white background, the bug is reproduced.
