--- Comment #1 from Elis Hirwing <elis at hirwing.se> ---
Hello,

I'm able to reproduce this or a very similar issue on NixOS on two different computers, both with NVIDIA GPU's (different generations though). Note that none of my setups are hybrid setups what so ever in two desktop systems.

I'm not sure what this minibrowser or primusrun things are, but I'm testing this in epiphany and as well in gnome3 settings panel for online accounts which happens to use webkitgtk as well.

For me the workaround by setting the environment variable WEBKIT_DISABLE_COMPOSITING_MODE=1 to launch epiphany fixes some of the broken websites.

Some broken ones I've seen so far:
https://duckduckgo.com/
https://google.se/
https://accounts.google.com/
https://elis.nu/ (my personal site)

Some sites that I see works:
https://git.elis.nu/ (my personal git hosting)

On all these broken ones I can even drag around the mouse to select text and then paste the selected text in a text editor, so the page is just blank. But it is rendered somehow.

So, I don't believe that this issue is directly related to the hybrid graphics, it seems to be nvidia in general.

This is one of the cards I've got with this bug:
01:00.0 VGA compatible controller: NVIDIA Corporation GP102 [GeForce GTX 1080 Ti] (rev a1)
        Subsystem: ASUSTeK Computer Inc. Device 85f1
        Kernel driver in use: nvidia
        Kernel modules: nvidiafb, nouveau, nvidia_drm, nvidia

The version of the nvidia driver is:
$  nvidia-settings --version
nvidia-settings:  version 387.22  (nixbld12@)  Mon Dec 11 21:29:29 UTC 2017
  The NVIDIA X Server Settings tool.

  This program is used to configure the NVIDIA Linux graphics driver.
  For more detail, please see the nvidia-settings(1) man page.
