Hi Thorsten, if you are still having this issue with liferea (or other
WebKit-based apps) I would like to try something else.

Can you build and run the attached program and paste the output?

It should be something like this:

  $ gcc -o drmdriver -I/usr/include/libdrm drmdriver.c -ldrm
  $ ./drmdriver 
  /dev/dri/renderD128: 'i915'

Also, if you can confirm what version of Debian you're using (trixie,
testing, sid, ...) and the exact versions of the webkit packages I can
maybe prepare a test build with a possible workaround.

Thanks!

Berto
