_InsertFenceFdNoGC errors on android


I am getting the following errors (displayed in the console) every frames in my application on android:

09-03 09:57:21.740: E/IMGSRV(15667): :0: _InsertFenceFdNoGC: Print the Gl2 Chk Null Value: 3 and 4

Any idea what would be causing it? I can’t find any information about it and what it means. I am quite sure I don’t do anything with fence but maybe the driver auto add some.


Hi Issam,

I don’t recognise this error message. What device are you running your application on? Can you share the graphics driver version with us (you can find instructions to query the version here).
