There are multiple problems with NVIDIA: * drm-modeset needs to be enabled in the kernel: this is a configuration issue, not related with WebKit. * NVIDIA GBM library needs to be installed: not all distros install it by default with the nvidia proprietary driver package. This is also a configuration issue in the end. * Videos don't work with the dmabuf video sink element. This is not specific to GTK4. The problem is that nvidia doesn't support linear buffers (yet), and we fail to create buffers with GBM. This can be solved in WebKit, I think. * On X11 with GLX context we fail to map the buffer for the same reason, we need a linear buffer to be able to map it in CPU memory, but nvidia doesn't support it. This can't be fixed in GTK3, but in GTK4 you can ensure GTK uses an EGL context by using GDK_DEBUG=gl-egl, and then mapping is not required (and it's a lot more efficient, so it's always desired anyway). I'm not aware of more issues. > > Am Mi., 15.
