+Subject: [PATCH] vl/dri3: fix a memory leak from front buffer
+
+Inspired by fix for mem leak of vdpau interop, resource_from_handle
+set texture reference count, that need to be decreased and released,
+recall there is a similar case for DRI3, that is with VA-API glx
+extension, there is temporary TFP(texture from pixmap), we target it
+through dma-buf. leak happens when without count down the reference.
+
+Checked and found with mpv vo=opengl case, there only one static TFP,
+the leak happens once, but for totem player using gstreamer VA-API glx,
+the dynamic TFP for each frame, so leak quite a bit.
+
+This fixes mem leak for mpv and totem.
