Serial Monitor: IDE becomes nearly unusable with really long lines.

[Spaceballs3000]

Describe the problem

IDE becomes sluggish over a few seconds.

To reproduce

Open Serial Monitor, run this code

void setup()
{      
  Serial.begin(115200); 
}
void loop()
{
 // Serial.println("------------------------------------------------------------------------------------------------------------------------------------------------------------");  // No issues with IDE slowness
 Serial.print("------------------------------------------------------------------------------------------------------------------------------------------------------------");  // With Serial Monitor windows open, IDE slowness will happen after a min or so. 
}

Hi @Spaceballs3000. Thanks for taking the time to submit an issue.

I see we have another report about this at #934.

It is best to have only a single issue per subject so we can consolidate all relevant discussion to one place, so I'll go ahead and close this in favor of the other.
