Description

I don't know what causes this but sometimes when I open the qam menu my gpu usage weirdly ramps up, I noticed it on Klonoa, a lightweight game that drops below 40fps even on 720p low without any reason.

I'll share some screenshots and the system report aswell.

Research direction

Start by reviewing the attached systemreport-20260710153720.txt and the two screenshots, then reproduce the behavior by opening the QAM menu while running Klonoa at 720p low. Done means identifying the cause of the GPU ramp and preventing the unexplained usage or resulting frame-rate drop.
