OrcaSlicer Version

1.9.0

OS version

Windows 10

Additional system information

CPU: AMD Ryzen 7 3700X
RAM: 32GB
GPU: Nvidia RTX 3060

Printer

Bambu Lab A1

How to reproduce

1. Slice a print
2. Change color scheme to "Filament" or "Speed"

Actual results

The GPU usage should be relatively low when viewing the sliced print with the default color scheme "Line Type" or any of the other schemes apart from filament or speed.
However, when filament or speed is selected, the GPU usage increases from about 1% max to around 48% max when not interacting with OrcaSlicer.
This occurs even when the window is not focussed and is not moused over/being interacted with, and also occurs when the window is minimised.
The high usage does not occur if a tab other than "Preview" is selected, even if filament or speed remains selected on the preview tab.

Expected results

The GPU usage should remain at the same level as when using all the other color schemes.
If this is not possible then the filament or speed color schemes should at least not have high GPU usage when OrcaSlicer is minimised or the window is not focussed.
