[bug] app window fails under Linux with Nvidia gpu

[doums]

Describe the bug

Hi, under Arch Linux, since today I hit an issue where the window app open with a blank screen and this message is spamming the terminal

AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer
AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer
…

journal logs:

[drm:drm_new_set_master] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Failed to grab modeset ownership

Note: My machine is NVIDIA gpu equipped, installed driver is 550.67-3

If I remove nvidia_drm.modeset=1 from kernel params, I get other logs

KMS: DRM_IOCTL_MODE_CREATE_DUMB failed: Permission denied
Failed to create GBM buffer of size 2524x827: Permission denied

Based on the logs I tried with KMS disabled completely (removing nvidia kernel modules and regenerating the initramfs) but without any success

Reproduction

npm create tauri-app@latest then cargo tauri dev (or npm run tauri dev)

Expected behavior

Oddly enough, I'm having similar problems trying to use https://github.com/tryphotino/photino.NET under Fedora (that's how I found this issue), both utilize gtkwebview so I'm guessing this might be a problem beyond Tauri/Photino.

Yup, as I thought, it's an issue with webkit2gtk being broken under 2.44 with Nvidia GPUs (https://gitlab.archlinux.org/archlinux/packaging/packages/webkit2gtk/-/issues/1)

For your local dev environment, you can add WEBKIT_DISABLE_DMABUF_RENDERER=1 in /etc/environment for the time beeing.

Hi, thanks for the info @LauraWebdev !

Thank you, this also fixed other apps such as yelp

Hi there, thanks that WEBKIT_DISABLE_DMABUF_RENDERER=1 does worked, my tauri apps works now. But unfortunately, my app becomes very slow, it takes 1 secs or even more every operation. If there's a complex animation based on JavaScript, my app looks like a PowerPoint lol. It's odd that this only happens when pnpm tauri dev, it works fine after I publish my package to AUR and install it.

I'm on Arch Linux with NVIDIA RTX 4060 laptop.

Any response will be very appreciate.

This doesn't really make sense to me unless your frontend is somehow super unoptimized in dev but for "simple" css statements that can't really be either.
The webengine doesn't have a dev and release mode and should have the same performance in dev and prod.

Really weird...
