Bug#1052055: Webkit output fully white

[R Pi]

Package: libwebkit2gtk-4.0-dev
Version: 2.42.0-1
Severity: important

I'm currently developing an app using Tauri. Since upgrading
libwebkit2gtk-4.0-dev from version 2.40.5-1~deb12u1 to version 2.42.0-1,
whenever I launch my app I'm getting the following messages:

KMS: DRM_IOCTL_MODE_CREATE_DUMB failed: Permission denied
Failed to create GBM buffer of size 1024x741: Permission denied
KMS: DRM_IOCTL_MODE_CREATE_DUMB failed: Permission denied
Failed to create GBM buffer of size 1024x741: Permission denied
KMS: DRM_IOCTL_MODE_CREATE_DUMB failed: Permission denied
Failed to create GBM buffer of size 1024x741: Permission denied
Failed to create EGL images for DMABufs with file descriptors -1, -1 and -1

The output of the webkit area is fully white, otherwise the content of the
webkit viewport appears to be working underneath (ie: I can interact with my app
but simply cannot see anything).

I was able to rollback to the previous version and keep working on my project
with the following command:

sudo apt-get install libwebkit2gtk-4.0-dev=2.40.5-1~deb12u1 \
libwebkit2gtk-4.0-37=2.40.5-1~deb12u1 \
libjavascriptcoregtk-4.0-18=2.40.5-1~deb12u1 \
gir1.2-webkit2-4.0=2.40.5-1~deb12u1 \
gir1.2-javascriptcoregtk-4.0=2.40.5-1~deb12u1 \
libjavascriptcoregtk-4.0-dev=2.40.5-1~deb12u1

I am using Debian GNU/Linux trixie/sid, kernel 6.5.0-1-amd64
and libc6 2.37-10. I am running the non-free nvidia-driver 525.125.06-2.
