Quickfix for performance problem

Comment 2 Moritz Nisblé 2015-06-15 13:38:40 UTC

Hi, I can confirm this.
The program is quite inefficient in placing the characters on the screen.
I profiled the program, found and fixed the most CPU-intensive situation.
Patch attached ...

Regards
Moritz

Hi,

I also confirm that. But in my case it doesn't matter if the window is maximized or not.
And can also confirm that Moritz's patch solves the problem.

The patch by Moritz Nisblé improves the performance a lot, without it ktouch is completely unusable for me. Still, even with the patch applied the UI still lags quite a bit behind when typing fast.

I tested the patch.
Without it, ktouch IS NOT USEABLE.

Version: 4:15.12.3-0ubuntu1

Sorry, but a type-trainer should be able to run on a Core 2 Duo. If a beginner can type faster then the program updates the display, you are seriously broken. Please apply the patch or fix the underlying problem.
