Hi,

     The current application use OPENGLES1.1 .When I use glTexDirectVIV / glTexDirectVIVMap / glTexDirectInvalidateVIV , Translucent layer layout which set by glBlendFunc(GL_SRC_ALPHA,GL_ONE_MINUS_SRC_ALPHA) is not as expected . But when I use glTexImage2D/glTexSubImage2D(But The efficiency is lower ),Translucent layer work as expected.

     So,how to solve this problem?

 

My current configuration:

          BOARD:IMX6Q_SABRESD

          BSP:3.14.52_LinuxYocto

          APP USE:Linux_framebuffer(FB,RGBA)+OPENGLES1.1

Thank a lot!:)

Hi xy

Please provide the sample code, Using GPU sdk samples glblend functions works as expected.

Maybe you are missing a glEnable(GL_BLEND)
