Dell Inspiron brightness constantly changing (sh.itjust.works)

When my laptop is on battery, the brightness changes depending on what's on the screen.

It changes when I maximize or minimize a window, when I open or close a tooltip, when the visual bell goes off in my terminal, when I move my mouse onto something, when I'm watching a video with no input.

It is extremely annoying and I would like it to stop happening.

All the solutions I have seen only work for a Dell Inspiron with Intel CPU, and mine is AMD.

System stats
Hardware: Dell Inspiron 15 with AMD Ryzen 7 CPU, 16GB RAM, AMD Radeon graphics.

Software: Debian GNU/Linux 13 (trixie) with Linux 6.12.43 kernel and KDE Plasma 6.3.6 desktop

There is no light sensor in my model.

When I aim a powerful lamp directly at it, the screen brightness does not change.

Light sensors are never mentioned in the online manual for my model.

Have you tried live booting another distro?

Maybe the new KDE Linux is a good canditate. It comes with the same DE and has the newest testing versions of everything and might have a bugfix included. Also it's arch based so there might be some default config that is different compared to what comes with debian.

It seems I can't boot from USB on this machine. The drive is recognized in the BIOS, but even when I add it to the sequence, it always boots from the main SSD. If I disable all options except the USB, it says "No bootable device found". When I start GRUB on my main drive, the USB doesn't show up.
