Title:
Webkit 2.42 and nvidia(?) drivers
Status in webkit2gtk package in Ubuntu:
Incomplete
Bug description:
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04.3 LTS
Release: 22.04
Codename: jammy
My machine recently installed updates to webkit and since doing that
some packages using webkit are not rendering the display correctly.
For example, running
/usr/lib/x86_64-linux-gnu/webkit2gtk-4.0/MiniBrowser
results in the output on the shell of
KMS: DRM_IOCTL_MODE_CREATE_DUMB failed: Permission denied
Failed to create GBM buffer of size 2048x1464: Permission denied
KMS: DRM_IOCTL_MODE_CREATE_DUMB failed: Permission denied
Failed to create GBM buffer of size 2048x1464: Permission denied
KMS: DRM_IOCTL_MODE_CREATE_DUMB failed: Permission denied
Failed to create GBM buffer of size 2048x1464: Permission denied
Failed to create EGL images for DMABufs with file descriptors -1, -1 and -1
And a display with just a blank window (attachment image-1.png).
There is a work-around, which is to force of the DMABUF, by running
WEBKIT_DISABLE_DMABUF_RENDERER=1 /usr/lib/x86_64-linux-
gnu/webkit2gtk-4.0/MiniBrowser
which results in the correct display output (attachment image-2.png).
Some searching on the web suggests this is related to a bad
interaction with the Nvida graphics driver. See eg:
https://aur.archlinux.org/cgit/aur.git/tree/GTK-Disable-DMABuf-
renderer-for-NVIDIA-proprietary-drivers.patch?h=webkit2gtk-imgpaste
