Unity Editor freezes certain system processes
I'm on Windows 10. At later phases of WebGL and Android builds, and when I compress textures or pack sprites, the Unity Editor uses up so many CPU resources that it freezes system processes such as Volume Mixer and even the mouse itself. The only workaround I've found so far is to set the editor's affinity to reduce the number of CPU cores it uses.
I'm on a very powerful laptop (Alienware 15 R3), so it is not simply a matter of my computer being underpowered. This is simply not acceptable, and Unity should not be using up so much of my CPU that I can't even use my computer while it's doing its thing. No other application I've used, including ones far more intensive than Unity, outside of driver updates have ever completely frozen my mouse or system processes.
I'm using Unity 2018.2.16f1, though I've also had this issue on prior versions including Unity 5.6. Are there any fixes or workarounds for this?
