Linux: unexpected gpu usage when suspend

I am on fedora 40 with 550.78 driver installed via this method: Howto/NVIDIA - RPM Fusion I’m on a laptop with nvidia gpu and intel apu

when I suspend my laptop (by closing the cover) or just when it gets suspended because of idle state, gpu usage seems to increase significantly. Laptop’s temperature also gets higher and fans starts.

I’m pretty sure this is not supposed to happen…

Sometimes I’m also unable to resume my system.

What should I check?
