With nvidia-dkms-470 need GSK_RENDERER=cairo WEBKIT_DISABLE_DMABUF_RENDERER=1

[Boris Gjenero]

I have an Nvidia GeForce GT 710, which requires the legacy 470 proprietary driver. Both foliate and epiphany-browser display improperly by default. Some user interface elements are missing, and e-book and web pages are totally blank. To fix this, I added the following lines to /etc/environment :
GSK_RENDERER=cairo
WEBKIT_DISABLE_DMABUF_RENDERER=1

In the past WEBKIT_DISABLE_DMABUF_RENDERER=1 was enough, but in Ubuntu 24.04 I also require GSK_RENDERER=cairo.
