Screen dimming while watching videos on Ungoogled Chromium

Whenever I am watching a video on Ungoogled Chromium, the screen just dims as if I was completely idle. This has never happened to me before in Manjaro, but I only switched to Ungoogled Chromium recently. Do you guys have any idea how to fix this? If it’s relevant, I am using the flatpak version and KDE Plasma.

Ungoogled comes as a flatpak now? Weird.

I guess I can mention I use the normal AUR package and I dont experience this behavior.

As an alternative to your issue, you can create an Activity dedicated for your video watching and set it like this in Power Management Settings.

Thanks. That helped with my Chrome issue as well.
