I am having a lot of issues with PhpStorm when moving quickly between windows (either PhpStorm windows or other widows like Chrome or other applications), it starts to use the CPU very aggressively and would make my fans loud.
This happens so much often even when quickly swapping with Command + Tab.
My question is what is it using the CPU for ? when I literally swapped away and back to PhpStorm within a single second. This behavior is also very repeatable.
I am opening multiple PhpStorm windows but I only use a couple of them most of the time, although this issue is also present when using one or two windows only.
