Hi!

It is working fine here on Fedora 40 ( in VM hosted on Arch Linux via VirtualBox )

Are you using wayland by any chance?

vrc-get/vrc-get#1405 (comment)

I'm using Fedora 40, running Wayland.

Original reporter is using Wayland

It works on my Fedora system (a real one, not a VM) too but the error somewhat sounds like something nvidia specific which i can't test.

Can you ask your users to run the app with the WEBKIT_DISABLE_COMPOSITING_MODE=1 and/or WEBKIT_DISABLE_DMABUF_RENDERER=1 env var(s) set? This typically helps with nvidia specific issues (though this specific error is new to me so no promises)

[debbie-drg]

Original reporter here! The system where I was having the issue does indeed have an nvidia GPU. I've just tried running the Tauri simple app on a laptop without an nvidia GPU also running Fedora 40 and the application indeed works. I'll try those env variables on my other system with the nvidia GPU and report back once I get home in a few hours.

[debbie-drg]

Running the application using the WEBKIT_DISABLE_DMABUF_RENDERER=1 env variable works.

[FabianLars]

Okay that's good i guess. It also means that this issue isn't really in our hands though :/ (as long as we keep using webkitgtk).

[anatawa12]

Is there anything I can do for improving this problem?

[FabianLars]

You could use std::env::set_var to set said env var for every user of your app. Of course that reduces performance for those where the renderer does work fine.

Alternatively, we can only wait for new webkitgtk releases. They are actively working on the renderer (which at the same time is the reason why webkitgtk broke for so many people in the first place).

[anatawa12]

I thought "as long as we keep using webkitgtk" means it's not fixable due to architecture or something hard to fix in webkitgtk.
but if it might be fixed, I'll just just wait for newer release. Thank you!
