            Bug ID: 180739
           Summary: [GTK] WebKitGtk does not work with NVIDIA systems with
                    NVIDIA driver and Accelerated Compositing
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Gtk
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: elis at hirwing.se
                CC: bugs-noreply at webkitgtk.org

I have two different stationary computers, both with NixOS and both with NVIDIA cards (but two different generations of cards) that I've tested on.

Both run webkitgtk-2.18.3 which seems to be latest stable.
Both run nvidia drivers of version: 387.22

Some, but not all websites fails to render to the screen. But the website loads and then I just get a dark gray box (same color as my gtk-theme has) over it. The website is loaded under it since I can see links if I hover the mouse over the gray area. And I can select text and copy paste it from the website.

The only workaround I've gotten to work is to supply this environment flag to my browser: WEBKIT_DISABLE_COMPOSITING_MODE=1

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)

This is the lspci output for one of my nvidia-cards:
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

I still think that this bug seems very similar to https://bugs.webkit.org/show_bug.cgi?id=176852, but people requested me to create a new issue.
