With wrap text enabled, typing characters into paragraph that is not fully visible on screen, causes visual flickering

[alt-grr]

Steps to reproduce:

1. Create text area, enable wrap text property
2. Type or paste single line that is long enough, so start of paragraph is off-screen
3. Typing or deleting more characters in that line causes very visible blinking and redraws

Something like this? I'm not sure if the Gif-making program recorded it well.

It's more clearly visible when text is inserted at the end of paragraph:

I'm not sure whether to label this as a bug or enhancement. :smile:

@JordanMartinez IMO "enhancement" is for new features/performance improvements, and this is clearly a rendering bug.

[JordanMartinez]

You're right. Not sure why I thought otherwise shrug.

@kuc In my GIF, the rendering isn't as bad as the one you posted. So, can you provide a reproducible demo of this rendering bug?

[alt-grr]

@JordanMartinez Try typing on the end of the text.

@kuc That probably makes the difference. When I sit down to fix this bug, I'll try that.
