Happens when running gnome in wayland mode, so whatever the display server is in that case (mutter?) or one of the libraries it uses. > Yeah, but you don't do rendering on dumb buffers. Like ever.

Well, wayland can use dma-bufs for buffer sharing between wayland server and wayland client. Dunno whenever it also does that for the software rendering case, and I have absolutely no idea how the buffer allocation code paths look like. But possibly it isn't known at buffer allocation time whenever a given buffer will be touched by a gpu at some point in the future? take care, Gerd _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
