I have A part of code in my Android App that gives me two diffrent Outputs for Two Adreno And Mali GPU:

For Mali GPU

For Adreno GPU

And this is the Code:

if (DRAW_DEST_POLY && DrawDest) {
gl.glEnable(GL10.GL_BLEND);
gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA);
gl.glLineWidth(2.0f);
gl.glPointSize(3f);
gl.glColor4f(0.8f, 0.0f, 0.0f, 1.0f);
gl.glVertexPointer(2, GL10.GL_FLOAT, 0, mBufDestVertices);
gl.glDrawArrays(GL10.GL_LINE_LOOP, 0, OpenglPoly.getNumPoints());
gl.glDisable(GL10.GL_BLEND);
}

I want the OutPut to be like what in Mali GPU is. (the problem is the inner shape that in second image has faded out)

Where does the color come from?

In the code you just set black color, but the shape is red?

is GL_COLOR_ARRAY enabled?

I'm guessing the problem might be with that

sorry this is the right code:

if (DRAW_DEST_POLY && DrawDest) {
gl.glEnable(GL10.GL_BLEND);
gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA);
gl.glLineWidth(2.0f);
gl.glPointSize(3f);
gl.glColor4f(0.8f, 0.0f, 0.0f, 1.0f);
gl.glVertexPointer(2, GL10.GL_FLOAT, 0, mBufDestVertices);
gl.glDrawArrays(GL10.GL_LINE_LOOP, 0, OpenglPoly.getNumPoints());
gl.glDisable(GL10.GL_BLEND);
}

Maybe try glDisableClientState(GL_COLOR_ARRAY); explicitly if you don't need it (and not already doing it)?

Just guessing, maybe it is enabled for some reason on the adreno and you get weird colors though that.

Looks very weird though, I notice also the frame has the same problem, and it looks to happen at the same X coordinate.

Is the frame drawn with 4 points one for each corner? If so, I don't think the problem is the color array...

I usually find the Adreno drivers to be the least compliant of all, with that said, I would not recommend using another GPU to confirm correctness. That said, I would verify using a third GPU is available, but who knows you may have encountered a driver bug..they are rampant in these mobile GPU drivers. Also, you are calling glVertexPointer, but I don't see where you are enabling/disabling the vertex array.
