Note: In the screenshot I see these in the panel, which is on the bottom, full
width
Kicker, Icons only task manager, a few system monitor applets, system tray,
clock, peek at desktop

I tested this on git-master and noticed similar but not identical behavior. I
measured GPU usage using nvtop
The system has an integrated AMD GPU
There is a Network Speed bargraph widget on the panel, as well as Total CPU
Usage, and Memory Usage

With the panel set to always show, GPU mem% was steady around .85Gi/2Gi and
GPU% was 0
With the panel set to auto hide, GPU mem% was the same, but gpu% was between 25
and 30% consistently, with no application windows open other than Konsole

Showing the panel dropped GPU% to 0, and allowing it to auto-hide sent it back
up to 25 - 30%

I'm not able to replicate with a default panel set to auto hide on another
git-master system with an integrated Intel and dedicated NVIDIA GPU. I noticed
that in the screenshot, there are a few system monitor widgets on the panel.
I added the Network Speed widget, but saw no change
I tried adding the same System Monitor widgets as on the other system I tested
on above, but still couldn't reproduce
