AVD "use host GPU" cause black screen when testing apps

Question

i created a new project of phonegap 2.7, and open the project by using eclipse and android emulator with use "use GPU option" , here is the screenshot

If i don't use "use GPU option", the logo can be displayed, but the upper background is still in black.

there should be a logo at center blinking and with a grey background (no black), any one knows what is the problem?

Answer 1

I've also been experiencing these rendering glitches, using Cordova 3.0.2.

This was appearing when using the Cordova CLI on OSX with Intel HAX CPU enabled and Host GPU Enabled.

As the OP said, disabling the Host GPU the rendering glitches appear to stop.

However, it appears with Host GPU enabled, the rendering glitches disappear quickly if I navigate through 2/3 screens; albeit reappearing each time the application is started.

E/GLUtils ( 2003): GL ERROR - after At the end of blitTileFromQueue()() glError (0x502)
E/TransferQueue( 2003): blitTileFromQueue ERROR: fboId 1, destTexId 12, srcTexId 3, textureWidth 256, textureHeight 256

Even once the rendering glitches appear to have stopped the error messages (above) are still being written to the log.

Not really an answer, but I'm happy to put up with the issues - now I know how to stop them if needed.

ETA : I've also tried to force H/W acceleration to be enabled via CSS (below) on the browser instance, incase that had some impact but to no avail.

body {
   -webkit-transform: translate3d(0, 0, 0);
           transform: translate3d(0, 0, 0);
}

This, in fact, caused the number of navigations required to resolve the glitches to increase.

Further tests show that it's not time dependant; not resolved by returning to the home screen; not resolved by scrolling; the only way I've been able to make them disappear to to navigate back/forth between a number of screens.
