Hi, have strange bug...

Once I switched to new MBP with touch bar, IDEA stuck for 1,2 sec if I pressing fn button + backspace or navigate arrow's.

 

Any suggestion how I can fix it?

 

Thank you!

Try getting the thread dumps with jstack when IDE doesn't respond (https://intellij-support.jetbrains.com/hc/articles/206544899) and report it at https://youtrack.jetbrains.com/issues/IDEA.

Hi, I'm experiencing the same issue but with Webstorm.
It really blocks me from working with it, since I cannot select a line using FN+arrow key, freezes almost every keypress.

Serge, sorry i can't provide dump...

For me issue was solved once I'm flush my Mac and install pure OSX High Sierra, I suppose issue can be reproduced if you install Sierra, IDE and after upgrade to High Sierra.

So maybe Denis can help us and get thread's dump?

 

Thank you!
