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

Disable HDR or high dynamic range support in the settings. I’ve seen something very similar on my laptop whenever that’s on.

Can't find that in KDE settings.

kscreen-doctor -o shows that my display is incapable of HDR.
