Problems with darktable container

I am referring to this image: linuxserver/darktable -

it works ok, no errors but the mouse cursor moves pretty jerky - I couldn’t do any image editing this way, its much to imprecise.

Does anyone else experience this? Just try to use the mouse cursor precisely. I have plenty of RAm and CPU and I haven’t even imported any images, just starting that container and accessing the GUI via browser feels very laggy.

I tried building my own darktable container based on GitHub - jlesage/docker-baseimage-gui: A minimal docker baseimage to ease creation of X graphical application containers which is a VNC based solution and that works much smoother but I’d rather not try and maintain my own images as I’m pretty new to this.
