An example I run into almost each day: run a non-trivial build in Visual Studio which consumes all available CPU cores. Now try to use the trackpad to scroll some random window content, it just doesn't work, at best you get a UI view that jumps around instead of smooth scrolling. AFAIK Windows is supposed to boost the CPU priority of the UI during user input, but apparently that doesn't work. AmigaOS also boosted the CPU priority of the UI during mouse movement, except it actually worked. PS: and instead of fixing the issue from the ground up in the OS (which admittedly is probably impossible) the VS team instead added a feature called 'Low Priority Builds': [1] https://developercommunity.visualstudio.com/t/Limit-CPU-usage-of-Visual-Studio-during/436208 https://developercommunity.visualstudio.com/t/Limit-CPU-usag...)
