How to reproduce

Open resource monitor
Place it above other windows or on different screen
Open OrcaSlicer with iGPU
Add a model to the plate
Slice it and switch to the preview tab
Move the cursor over it with no additional actions and see the GPU load

Actual results

GPU load hits 100%. The interesting thing here is that 780m is almost twice as powerful as my previous GTX 1050, but I had no performance issues with it.

Expected results
