Repro steps:
|
||
|
|
|
||
|
|
build, install and run the attached test program TestViewport.apk
|
||
|
|
|
||
|
|
Run on Sapphire with Froyo.
|
||
|
|
|
||
|
|
The program clears the screen to blue, then draws a full screen white quad that
|
||
|
|
is alligned to the screen.
|
||
|
|
(Therefore the whole screen should appear to be white.)
|
||
|
|
|
||
|
|
|
||
|
|
Note that screen is all white.
|
||
|
|
|
||
|
|
Rotate screen 90 degrees.
|
||
|
|
|
||
|
|
Expected: screen is still all white.
|
||
|
|
|
||
|
|
Actual: screen is blue with offset white rectangle.

This bug only happens on Sapphire, it works correctly on Passion.
|
||
|
|
|
||
|
|
What happens:
|
||
|
|
|
||
|
|
I think the bug is that the gl.glViewport() call in onSurfaceChanged() is
|
||
|
|
being ignored by the OpenGL driver.
|
||
|
|
|
||
|
|
NOTE: If a gl.glViewport call is added at the beginning of the onDrawFrame()
|
||
|
|
call (which means it is called before every draw), the program runs correctly.
