+Subject: [PATCH] plugins/screencast: call ItemRenderer::begin/endFrame
+
+The OpenGL renderer references the explicit sync release points for client buffers
+during rendering, and releases them in endFrame. If endFrame never gets called though
+(for example because we're doing direct scanout) then the release points never get
+signaled, and the client very quickly runs out of buffers to use and freezes.
+
+BUG: 495287
+
+
+(cherry picked from commit b1031ea63eaa8c9bf5c70157d1b6bf8eb0f5a74a)
