            Bug ID: 91395
           Summary: OpenGL functions block for serveral ms when used with
                    EGL
           Product: Mesa
           Version: git
          Hardware: Other
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i965
          Assignee: idr at freedesktop.org
          Reporter: fernetmenta at online.de
        QA Contact: intel-3d-bugs at lists.freedesktop.org

We just moved Kodi (http://kodi.tv/) from glx to egl. With vsync enabled glx
was used to block in glxSwapBuffers. EGL shows timing issues. Instead of
blocking in eglSwapBuffers it blocks in subsequent gl calls like glColor for
several ms. It even does so if I put a glFinish right after eglSwapBuffers.
Rendering overlays on top of video leads to missed frames because it slows down
rendering even more.
