please can you upload your dump to some file server and provide a link here? You can use ftp://ftp.intellij.net/.uploads/, for example - anonymous login, .uploads directory has no permissions to list/download files, only for upload

Apologies, never used that service before and it seems will never use again.
Here's the link to google drive, hopefully it works.

Thanks!

does the issue occur when the built-in terminal is focused?

Please can you recreate the issue and provide your ~/Library/Logs/WebStorm<version> directory content?

Sorry, but the log file is not helpful here... I need thread dumps from the Logs directory

Well... Doesn't look like freezing. A minor delay on file deleting...

Can you describe the sequence of actions that lead to the issue? And, BTW, what actions are Fn+arrow keys shortcuts assigned to in your keymap?

I'm not sure what file deleting you're talking about, but I sure see Freezes when I use Fn+Arrows and Fn+Delete Actions:

Move Caret to Line End = Fn+Right Arrow

Move Caret to Line Start = Fn+Left Arrow

Delete = Fn+Delete

 

The sequence of actions:

1. Open Webstorm

2. Try to delete a character with Fn+Delete

3. Webstorm is Frozen for 2 seconds

4. The characted is deleted.

 

For example if I use Atom:

1. Open Atom

2. Try to delete a character with Fn+Delete

3. Atom deletes the character

So it's not frozen, just busy for few seconds... dumps are not helpful then. Please try taking CPU snapshots (https://intellij-support.jetbrains.com/hc/en-us/articles/207241235-Reporting-performance-problems) when performing the actions

Oh, Ok.

I thought that being unable to respond to user actions means frozen, but I'm not an expert.
Thanks for the instruction, Elena, I will try to take the CPU snapshots tomorrow.

Hello, Elena.

I've captured the CPU snapshots using the instruction provided above, when performing the same actions described above.
Here's the zip archive:

Almost all time is spent in native method (com.apple.laf.ScreenMenu.invokeOpenLater() ):( Weird.

Can you check if the issue persist if you re-map these actions to different shortcuts?
