good xorg.log
The problem is that epoxy_has_gl_extension() is called before the context is made current (or even created). Every OpenGL API call requires a current context, including the one for getting the list of supported extensions. Ouch, did not notice that the eglMakeCurrent call is after the extension checks. A patch can be found here [1], if it hasn't hit your inbox.

Created attachment 118433 [details] screenshot Hi. After 'glamor: move GL_OES_EGL_image check next to EGL_EXT_image_dma_buf_import', my screen is corrupted upon login. I've attached a screenshot of what it looks like. Let me know if you need any more info. Thanks, sarnex
