The issue is still happening

This issue is due that a GL variable is getting updated in OnMeasure (which is running on the main thread) and onDraw( which is getting called on the GLRenderer Thread) Race condition for updating this variable is causing this issue.
In my case I was getting this crash when I was doing the resizing of the GLSurfaceView. 1 out of 3 time doing resizing it is hitting this window. And was getting this crash.

java.nio.BufferOverflowException at java.nio.Buffer.nextPutIndex(Buffer.java:536) at java.nio.ByteBufferAsFloatBuffer.put(ByteBufferAsFloatBuffer.java:109) at com.otaliastudios.opengl.draw.GlRect.setRect(GlRect.kt:63) at com.otaliastudios.opengl.draw.GlRect.setRect(GlRect.kt:47) at com.otaliastudios.zoom.ZoomSurfaceView.onContentOrContainerSizeChanged(ZoomSurfaceView.kt:238) at com.otaliastudios.zoom.ZoomSurfaceView.onMeasure(ZoomSurfaceView.kt:215) at android.view.View.measure(View.java:27129) at androidx.constraintlayout.widget.ConstraintLayout$Measurer.measure(ConstraintLayout.java:811)

    The variable which is causing this is :
    ` glTextureRect.setRect(rect)` -> it is getting modified in onContentOrContainerSizeChanged() and also in the onDraw.
    
    One solution that comes to my mind is to thread safe this variable. if writer of this lib can make this change, it will be very much beneficial.
