PhpStorm 2017.3 uses 100% CPU Follow
PhpStorm 2017.3 is constantly using 100% CPU even if no processes are running.
I already tried to invalidate cache and restart but the problem persists after the indexing is done.
Isn't there a PhpStorm specific task manager to see what it's doing? (like the one on Chrome)

No, unfortunately there's no task manager.
Current tasks are displayed in a View > Status Bar (a bar in a bottom of IDE). It might show "indexing ..." or "scanning files to index".
Is your project on a local drive? Are there any symlinks? Did you try to disable all custom pluings (Settings/Preferences > Plugins > Show: Custom)?
I've got the same issue.
Status Bar is empty but phpStorm is going crazy in the background.
Out of nowhere it pushes all my 16 threads to 50% load for like 2 minutes and goes back to 0 afterwards.
Never had this before... super strange
Please use "Submit a request" link at the top of this page and provide CPU snapshot/idea.log there. See https://intellij-support.jetbrains.com/hc/en-us/articles/207241235-Reporting-performance-problems
Each person will most likely have different reasons for such behaviour (machine/config specific cases). There is no single solution for "me too" cases.
I just found out that the high CPU usage is caused by a javascript file.
Cleaning it up, I also found that is specifically this line of code that generates the high CPU usage:
$('<div>').appendTo($form);i have sample issues, cpu verry hight http://prntscr.com/j4kp5u
I just changed the .idea directory's permission.
