Greetings,

I have a case here where inside a call to glClear on OpenGLES 3.1 suddenly a malloc of about 33 MB seems to be performed. Anyone with insight in the drivers here who can tell me when such a thing might be possible?

System is Aarch64Linux, GX 6650 GPU.

Regards.

Hi Desperado,

Thank you for reaching PVR Developer forum.  
I can see you already reported to our internal developer portal with detailed memory logs. I am already in touch with our DDK team to address this.

Best Regards,
