Looks like the bug has made it's way to GitButler. Getting this exact error trying to start it.

Thought it was this error at first, but the problem persists after removing the window-state file

Edit: this is giving me nvidia-problem vibes. Are you using nvidia?

this is giving me nvidia-problem vibes. Are you using nvidia?

Can confirm on my end that it is related to NVIDIA. I got the same error on my NVIDIA-only machine.

Here is the log with WAYLAND_DEBUG=1, https://pastebin.pl/view/5fd8b401

[2610755.730] {Display Queue} wl_display#1.error(wp_linux_drm_syncobj_surface_v1#50, 4, "explicit sync is used, but no acquire point is set")
Gdk-Message: 04:05:57.352: Error 71 (Protocol error) dispatching to Wayland display.

Edit: My machine is running Arch Linux, NVIDIA 560.35.03, NVIDIA EGL Wayland 1.1.16.

I recently migrated over to wayland, and came across this same issue (though in a tauri v2 app)

A temporary solution is to use

WEBKIT_DISABLE_DMABUF_RENDERER=1 pnpm tauri dev

found from here

This happens for me when running Webkit2gtk's MiniBrowser example app, so it's likely an upstream issue. I've filed https://bugs.webkit.org/show_bug.cgi?id=280210 .

[Zamoca42]

fixed some of the issues causing “Error 71 (Protocol error)” in tauri-apps/tao#979.
I believe the update will be applied in the next version after tao 0.30.2.

[AmeerArsala]

is this fixed?

[lll-Death-lll]

__NV_DISABLE_EXPLICIT_SYNC=1 also fixes the issue for me
