Clearing GL Error

[adeldolgov]

I have SupportMapFragment and CardView above it. BlurBehindLayout is situated inside this CardView.
Im getting this log everytime :
W/GLConsumer: [SurfaceTexture-3-17437-2] bindTextureImage: clearing GL error: 0x500
What does it mean? How to fix it?

Layout is :

<no.danielzeller.blurbehindlib.BlurBehindLayout
            android:foreground="#ADFFFFFF"
            android:visibility="gone"
            android:id="@+id/blurBehindLayout"
            android:layout_width="match_parent"
            android:layout_height="56dp"
            android:layout_marginBottom="8dp"
            app:blurRadius="10.0"
            app:updateMode="continuously"
            app:useTextureView="true"
            app:blurTextureScale="0.2"
            app:useChildAlphaAsMask="false">
            <!-- Add Children -->

</no.danielzeller.blurbehindlib.BlurBehindLayout>

I'm actually not sure how to fix this one. It seems to be simlar to this bug: yulu/ShaderCam#1 But we are allready using glBindTexture(GLES11Ext.GL_TEXTURE_EXTERNAL_OES not glBindTexture(GL_TEXTURE_2D when using a surfacetexture. So my guess is that is because we are first binding a regular texture to glActiveTexture(GLES30.GL_TEXTURE0) and do a render. Then we bind a surface texture to GL_TEXTURE0. Which causes the error log although things work as intended.
