My webkit2gtk programs and the MiniBrowser example both fail to start on Wayland on my Nvidia desktop. They print the following error and exit:
Gdk-Message: 17:14:30.589: Error 71 (Protocol error) dispatching to Wayland display.
Running the programs with `WEBKIT_DISABLE_DMABUF_RENDERER=1` fix the issue.
Running the program with `WAYLAND_DEBUG=` shows this line at the end:
[4192651.933] {Display Queue} wl_display#1.error(wp_linux_drm_syncobj_surface_v1#55, 4, "explicit sync is used, but no acquire point is set")
Tested with the v2.46.0 package for Arch Linux, and Nvidia proprietary driver version 560.35.03.
Probably related to https://bugs.webkit.org/show_bug.cgi?id=262607 . I'm using webkit2gtk via wry, which tauri also uses, and they have an issue here: https://github.com/tauri-apps/tauri/issues/10702 , so I don't think I'm the only one.

Running under X11, either via setting `GDK_BACKEND=x11` or by running an X11 desktop env, also does not work, but has somewhat different symptoms. The webview screen is all white and the application prints the following message:
Failed to create GBM buffer of size 1024x730: Invalid argument
The underlying page controls still work, but aren't visible.
Setting `WEBKIT_DISABLE_DMABUF_RENDERER=1` fixes this issue.

What compositor is this? gnome-shell/mutter? What GTK4 version? From WebKit we just render into the gtk widget without using any wayland specific thing.

I've tested this with Gnome 47.0.1 and Plasma 6.1.5; it happens under both. GTK4 version 4.16.1.
