Greetings,

I’m running an EGL app with PVRVFrame libraries from the 2017 SDK. When I enable mesa gl debug mode with export MESA\_DEBUG=1 I get lots of errors as follows:

Mesa: User error: GL\_INVALID\_OPERATION in unsupported function called (unsupported extension or deprecated function?)  
Mesa: User error: GL\_INVALID\_ENUM in glEnable(GL\_POINT\_SPRITE)

The glEnable call seems to be part of glDrawArrays calls which don’t render point based geometry.

Do you know this phenomenon? Regards

Hi,

possibly PVRVFrame doesn’t support these old OpenGL functions. I’d say ignore the errors or don’t use such functionality.

bests,

I don’t use GL\_POINT\_SPRITE directly. I wonder if PVRVFrame does.
