| 2 | |
| 3 | build, install and run the attached test program TestViewport.apk |
| 4 | |
| 5 | Run on Sapphire with Froyo. |
| 6 | |
| 7 | The program clears the screen to blue, then draws a full screen white quad that |
| 8 | is alligned to the screen. |
| 9 | (Therefore the whole screen should appear to be white.) |
| 10 | |
| 11 | |
| 12 | Note that screen is all white. |
| 13 | |
| 14 | Rotate screen 90 degrees. |
| 15 | |
| 16 | Expected: screen is still all white. |
| 17 | |
| 18 | Actual: screen is blue with offset white rectangle. |
| 19 | |
| 20 | This bug only happens on Sapphire, it works correctly on Passion. |
| 21 | |
| 22 | What happens: |
| 23 | |
| 24 | I think the bug is that the gl.glViewport() call in onSurfaceChanged() is |
| 25 | being ignored by the OpenGL driver. |
| 26 | |
| 27 | NOTE: If a gl.glViewport call is added at the beginning of the onDrawFrame() |
| 28 | call (which means it is called before every draw), the program runs correctly. |
