[4.5] The Output Log degrades performance
In 4.5 preview, the Output Log causes a big performance hit. The larger the log, the worse.
Hiding the Output Log solves the issue. Clearing the Output Log solves the issue until it grows again.
In my case, the editor can go from 120fps to 20fps in just a few minutes with an empty scene and just one log per frame.

The output log is our most extreme example of a multi-line editable text, however it shouldn't be causing that level of performance degradation. Given that it only happens when the log is visible, it's most likely something in OnPaint() - I'll take a look.
For reference, what spec is your machine?
