Descriptive Problem Summary:
After doing a replace all after the Line Numbers update (496.1144), the code editor does not update properly, leaving artifacts from the before-replace version. Clicking on the line updates ONLY that line. Select+ALL will update the entire thing. Scrolling left and right/up and down updates part of the window, the part that is obscured by the scrolling, still leaving artifacts from before the replace all.

This bug occurs with both line numbers toggled on and off.

Numbered Steps to Reproduce Problem:
1. Create environment with lots of something (slashes? keywords?)
2. Replace all instances of that something with something else
3. It doesn't update update
4. Click on line to update it, or scroll bar around.

Expected Results:
The code editor to automatically update after a replace/all.

Actual Results:
The code editor takes the appearance of what it looked like before the replace all, until you force it to update by clicking, scrolling, or select ll.

Does the problem occur:
Every time? Or how often? Every time.
On other computers? Yes, verified by user Keeth.

When does the problem NOT occur?
No idea, I did come across a time when it didn't happen, once. But it only didn't happen once, so I have no clue what caused it to work.

Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? It's only occurred in this version.

Workarounds:
Select + ALL updates the entire editor.
