Have you tried libgallium 25 from Trixie-backports? I have observed that 
sometimes when you use a backports kernel you need adequate backported 
libraries.
 From the modification journal of mesa-libgallium (trixie-backports):
"[...]
   * Lower libdrm-dev to 2.4.124-1 to match the version in Trixie
[...]"
which suggests that mesa-libgallium from Testing is likely to create 
problems in Trixie.

I would advise you against performing dist-upgrades of a stable Debian 
distro: dist-upgrades are meant only for major version upgrades, and 
even then, they are meant to take place only after an ordinary upgrade.

Possibly you could also assert if you need at all backports and 
fasttrack repos for other purposes, because your hardware being not the 
latest (at least the graphic card), it does not seem to need that. And 
the reliablity of a Stable Debian is greater than that of a 
Stable+backports(+fasttrack) one
