But what did you *install* from backports? Simply enabling the repository
doesn't do anything. Backports are pinned in such a way that they are
never installed by default. You must explicitly install each package.

OK. First thing I wonder is whether you have installed the
firmware-amd-graphics package (from the non-free repository). But even
then, I don't know whether it has the correct firmware for your device,
because I couldn't find "R7" or "Oland" in the package description. I
do see "oland" a few times, but...
* Radeon HD 8500/8600/8700 series CE microcode (amdgpu/oland_ce.bin)
* Radeon HD 8500/8600/8700 series K SMC microcode
(amdgpu/oland_k_smc.bin)
* Radeon HD 8500/8600/8700 series MC microcode (amdgpu/oland_mc.bin)
* Radeon HD 8500/8600/8700 series ME microcode (amdgpu/oland_me.bin)
* Radeon HD 8500/8600/8700 series PFP microcode (amdgpu/oland_pfp.bin)
* Radeon HD 8500/8600/8700 series RLC microcode (amdgpu/oland_rlc.bin)
* Radeon HD 8500/8600/8700 series SMC microcode (amdgpu/oland_smc.bin)
* Radeon HD 8500/8600/8700 series UVD microcode (amdgpu/oland_uvd.bin)
I don't know whether any of those is intended to match your device.
Checking "dmesg | grep -i firmware" would be good.

So you grabbed a kernel image from backports, at least. That's probably
a good step. But this doesn't tell us whether you also grabbed the X
server (or Wayland), Mesa, firmware, etc.

Upgrading to bullseye is probably wise for this new a device. If nothing
else, it would save you having to figure out all of the backported
packages you need.
Googling gave me a page that's not directly related to Debian:
https://linux-hardware.org/?id=pci:1002-6613-1458-22b0
And an unanswered Debian bug report: https://bugs.debian.org/966420
But the person reporting that bug was using a buster kernel, where you
are using a backported kernel. So perhaps that doesn't affect you.
