Expected Behavior

Editing text is smooth and responsive.

Actual Behavior

Editing text is unresponsive and often pauses/freezes. Checking Goland Activity Monitor window it shows a spike in CPU for HCL plugin during pauses.

This happens when no other plugins are installed, other than the HCL plugin. Uninstalling HCL plugin restores normal text editing behaviour.

Have created a video to demonstrate
