Description mvowada 2015-06-29 07:26:33 UTC 
I've noticed a considerable CPU usage:
A) when I type on a multiline text frame, as well as
B) when I move the multiline text frame over the canvas (please, see video below).

- Krita: 2.9.5 (git 9fe0557)
- Ubuntu 14.04 - Unity
- Core2 Quad CPU

Reproducible: Always

Steps to Reproduce:
Either case:
1. enter some multiline text
1. move a multiline text box

Actual Results:  
Considerable CPU usage and lags.

Expected Results:  
Lower CPU usage and responsiveness.

Test with OpenGL enabled and disabled.

Hello Boudewijn,
It seems it happens in either case, that is with OpenGL enabled "AND" disabled (see PNG file in attachment).
Tested with:
- GeForce 9800 GT/PCIe/SSE2 Video card
- OpenGL version string: 3.3.0 NVIDIA 331.113

Let's track all the multiline text tool bugs in 306181 -- it needs rewriting in any case.
