+Subject: [PATCH] Start on Wayland with an NVIDIA GPU
+
+With the NVIDIA driver under Wayland, WebKitGTK's DMA-BUF renderer takes
+the window down at start with "Error 71 (Protocol error) dispatching to
+Wayland display", so the .deb and .rpm did not open at all there. The
+AppImage forces X11 and never hit this. WEBKIT_DMABUF_RENDERER_FORCE_SHM
+is now set at startup when the NVIDIA DRM module is loaded, which hands
+frames over through shared memory and still renders on the GPU. A player
+who set it, or WEBKIT_DISABLE_DMABUF_RENDERER, keeps their value.
