Flickering Run/Debug Icon


The icon in my Run/Debug toolbar flickers intermittently when I'm typing in the editor.  This seems to happen regardless of which icon is loaded in the toolbar and it only seems to occur while I'm typing.  It has become so distracting that I finally figured out how to record a GIF of it.

I regularly use GoLand and I believe I've seen it occur there as well.

If this isn't a known issue, where should I file a bug?

Can you share the content of the scratch file? Or maybe the screencast of reproducing? 

I tried to reproduce that, but the icon is always grayed out for me in scratches. 


It isn't just Scratches... it's anything.  Here's an example with a Gulp configuration.

The flashing doesn't seem to have anything to do with what type of file I'm working in.  Typically if I'm typing pretty fast, it will flash as soon as I slow down... as if something is catching up to what I've been typing.

I don't feel comfortable sharing a full screencast on this forum but I don't mind sending one to you directly (or through a bug).  I have one ready to go.


You can share it privately by creating new YouTrack ticket: https://youtrack.jetbrains.com/newIssue?project=IDEA

Please disable all downloaded plugins to be sure it is caused by IDE itself. 

Thank you.
