Blank window #2977

infinitebugs32 · 2023-10-11T11:04:01Z

Description

Yesterday my app worked just fine. This morning, after making no changes to the code, I executed wails dev and it resulted in a full gray window. However when I randomly move my mouse on the window I can see the tooltips of my app.
Can't even open the dev tools in the wails window. Works in the browser though (wails dev --browser).
My main.go does correctly include the assets:

//go:embed frontend/dist
var assets embed.FS

Wails dev output:

When I try to run the binary after building:

To Reproduce

wails init -n testwebkit
wails dev

Expected behaviour

I expect a properly working Wails app window

Screenshots

wails dev --browser

Attempted Fixes

Remove webkit packages. Break my system. Cry. Reinstall webkit. Reinstall Gnome. No solution.

System Details

Me:
Kubuntu 22.04
Wails v2.4.1
Vite v3.1.8
Webkit: libwebkit2gtk-4.0-37 libwebkit2gtk-4.0-dev

My co-worker who has the same issue:
Arch Linux (kernel: 6.5.6-arch2-1)
Wails v2.6.0
Webkit: webkit2gtk 2.42.1-1 webkit2gtk-4.1 2.42.1-1 webkitgtk-6.0 2.42.1-1

Additional context

Similar to #2975 and #9

Same issue for every Wails project (with this Archlinux config). Not just for a new created project.

leaanthony · 2023-10-11T12:35:51Z

I wonder if your systems silently upgraded some deps. There's no reason anything should change overnight with your code or deps....

leaanthony · 2023-10-11T12:40:46Z

Have you tried disabling compositing? https://bugs.webkit.org/show_bug.cgi?id=180739

You could also adjust this: https://wails.io/docs/reference/options/#webviewgpupolicy

infinitebugs32 · 2023-10-11T13:02:42Z

linux.WebviewGpuPolicyNever does the job . However I will keep looking into it to find a solution that doesn't require disabling hardware acceleration. Could you leave this issue open ?
Thank you !

What will be the permanent fix?

Standardisation in Linux distros 😅

zerollzeng · 2023-10-13T16:09:57Z

I saw similar issue when open my cisco anyconnect client. so I search the error and I found this. I have a WAR that use WEBKIT_DISABLE_DMABUF_RENDERER=1 /opt/cisco/anyconnect/bin/vpnui or export WEBKIT_DISABLE_DMABUF_RENDERER=1 before launch the application. I'm managing to find a thorough solution.

leaanthony · 2023-10-13T20:05:02Z

Thanks for the info. Sounds like an ecosystem wide issue 😞

leaanthony · 2023-10-13T20:28:56Z

If anyone who is having the issue is comfortable with local Dev, then setting this environment in this function might fix the issue: https://github.com/wailsapp/wails/blob/master/v2/internal/frontend/desktop/linux/frontend.go#L139

If it does we can make it a flag.

db47h · 2023-11-02T16:12:44Z

There are several webkit bug reports related to this:
https://bugs.webkit.org/show_bug.cgi?id=228268 and https://bugs.webkit.org/show_bug.cgi?id=261874#c32

This is clearly webkit/nvidia related and there's no real fix yet (even the nv drivers update mentioned in 281874 does not fix this bug for me).

IMO, the best way to tackle this in wails and its ecosystem is:

add a bool command line flag like -webkit-dmabuf-renderer set to false by default (which would set WEBKIT_DISABLE_DMABUF_RENDERER=1 by default on linux).
end users who can read a README and need better performance can then re-enable it.
keep this issue open until the upstream bug is resolved, then change the default flag value to true

This way, end-users won't even see the bug and this would put less pressure on devs.

Assuming that very little client code uses the options.App.Linux field, I my have an even simpler solution:

diff --git a/v2/internal/frontend/desktop/linux/window.go b/v2/internal/frontend/desktop/linux/window.go

Then add a warning in the docs for linux.Options.WebviewGpuPolicy about the potential issues and the default behavior. The only problem I see is that not setting options.App.Linux would have a different behavior than providing an empty {}&linux.Options.

leaanthony · 2023-11-03T03:04:21Z

Happy to accept a PR on this. Agree - it's probably the best way forward.

In NewWindow, set options.Linux.WebviewGpuPolicy to WebviewGpuPolicyNever if options.Linux is nil, disabling GPU acceleration by default on linux until the upstream bugs https://bugs.webkit.org/show_bug.cgi?id=228268 and https://bugs.webkit.org/show_bug.cgi?id=261874 are fixed.

db47h · 2023-11-03T17:21:55Z

Here you go #3027.

I ran into this issue trying use webkit2gtk on arch linux (with an nvidia card) and I was able to fix it without setting WEBKIT_DISABLE_DMABUF_RENDERER=1.

Here is how I fixed it:

Check if you have modesetting enabled via

 cat /sys/module/nvidia_drm/parameters/modeset

If you see printed N then you need to enable it with

 echo options nvidia_drm modeset=1 | sudo tee /etc/modprobe.d/nvidia_drm.conf

Restart your computer

Thank you so much @nobane this works perfectly on my Arch machine.
