logs for "Learn OpenGL ES 2.0" Samples (debug.egl.trace 1)

Hi,

I'm running the latest version of Android-x86 ( Kitkat RC1 ), but replaced
bundled Mesa 9.2.1 by 10.0.4 and latter by 10.0.5 (See the procedure on
https://groups.google.com/forum/#!topic/android-x86/lKPmDXtNzjM).

This replacement gives support to my Radeon (7660D IGP). However, some OpenGL
ES 2 apps have a problem when rendering a sequence of moving objects. Seems
previous frame is not clean, keeping a trail / track of the previous image.

A example of this is "Learn OpenGL ES 2" sample tutorial apps
(http://www.learnopengles.com/). I attached 2 pics showing the problem.

Other apps using OpenGL ES 2 render correctly without problems. I got a picture
from an app called "Live Ocean Benchmark", which works perfectly. Also, Play
Store games like "Lawless" and "Angry Birds Star Wars" works correctly, except
for the very first logos (they also have this redraw problem).

I turned on "debug.egl.trace" and generated logs to compare a working app (Live
Ocean Benchmark) with a problematic one (Learn OpenGL ES 2). I attached them.

Could you say if this is a known problem with these versions of OpenGL? 
Couldn't test 10.1 on Android source tree to compare (Compiling errors).

Here's the full specs of machine/environment I tested:
CPU: AMD A10 5800K
VGA: Radeon 7660D (IGP - Integrated to the processor)
MEM: 8 Gb RAM (Corsair Vengeance 1600)

SO: Android-x86 ("KitKat - RC1" - Kernel 3.10.30 - 32 bits)
Mesa versions tested: 
 - 9.2.1 (Doesn't support my IGP) 
 - 10.0.4 (problem described above)
 - 10.0.5 (same as 10.0.4)

"OpenGL driver version" on Android Settings show this:
GL Vendor: X.org
GL Renderer: Gallium 0.4 on AMD ARUBA
GL Version: OpenGL ES 2.0 Mesa 10.0.4

Note: I created a bootable iso image to test it:
