I am currently using the PhpStorm 102.206 EAP on Windows 7. With this new version I have noticed that the editor misses some character input while I type. I haven't had this problem in previous versions. I've tried turning off all inspections but it did not make a difference.
If I type a simple string like "testtesttesttesttesttesttest" into the editor, I end up with something like "testesttsttettsttestst" with obvious characters missing. I've tried typing in notepad just to make sure it wasn't a problem with my keyboard.
Not sure if anyone else is having this problem but I thought I'd throw it out there,
