            Bug ID: 499373
           Summary: Spectacle wakes up the dGPU and keeps it powered on if
                    nvidia-vaapi-driver is installed
    Classification: Applications
           Product: Spectacle
           Version: 24.12.1
          Platform: Arch Linux
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: General
          Assignee: noaha...@gmail.com
          Reporter: v19930...@gmail.com

  Target Milestone: ---

SUMMARY
On an AMD iGPU + Nvidia dGPU setup Spectacle will power on the dGPU when it's
launched and will keep it active while open if and only if nvidia-vaapi-driver
(libva-nvidia-driver on arch) is installed. This results in increased start
time and power draw.

STEPS TO REPRODUCE
1. Install nvidia-vaapi-driver
2. Launch spectacle

OBSERVED RESULT
dGPU will get powered up and stay that way until spectacle is closed. Spectacle
will also launch slower than it does without nvidia-vaapi-driver.

EXPECTED RESULT
dGPU will stay powered down or at least will power down soon after spectacle
starts.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 
KDE Plasma Version: 6.2.5
KDE Frameworks Version: 6.10.0
Qt Version: 6.8.1

ADDITIONAL INFORMATION
Frustratingly, neither nvtop nor nvidia-smi show spectacle as using the dGPU,
making it relatively hard to understand why is it staying powered up.
