intellij, The source preview is slowly when my mouse point is over right's scroll in IntelliJ SDK
It's a useful feature for quickly showing preview mini source code.
But I don't want to work this function. My Intellij Program was slowly.
Do you know how to cancel it? I can't find disable this feature Because I don't know what's name of feature.
Do you help me to do disable feature or what's name or Performance tuning?
