X11 eglCreateImageKHR implementation
Hi, While working with gnome-shell (X11, cogl & mutter doing window compositing) we see a strange issue when eglCreateImageKHR() is used to get an OpenGLESv2 texture of an X11 window pixmap. We...

Hi, For eglCreateImageKHR(..EGL_NATIVE_PIXMAP_KHR..), the driver will use XGetGeometry to get the depth, and DRI2GetBuffers to get the width, height and other info from pixmap. Can you share...

Hi dsd, Did Frank's reply solve the issue for you or do you need more information. If the latter would you be able to supply some sample code as Frank suggests?

Thanks for the info. I was curious where it gets the actual pixel data, but I think your response indicates that: it receives the UMP ID from DRI2GetBuffers (via the returned DRI2 buffer name), and can...

I will see if I can find some time to come up with a simple test case. It is one of those problems that is hard to put a finger on exactly which conditions cause it.

I think this may just be a bug with the xf86-video-fbturbo DDX. As Frank points out, it is the DDX that is responsible for inputting the window contents into the GL system, and this issue has gone away...

May I ask for help on (example source code / documentation) on how to create an EGLImage usiing eglCreateImageKHR on X11? I am currently using odroid-xu3 running Ubuntu 15.04. I already post details in...
