Description 1234qwer 2016-04-26 18:12:24 UTC

After upgrading ubuntu from 14.04 to 16.04 ktouch slows down. Now it takes up to a half second before a keypress is registered.

Reproducible: Always

Steps to Reproduce:
1.upgrade ubuntu from 14.04 to 16.04 or install ubuntu 16.04 direct
2.install / start ktouch
3.Start Training

Actual Results:  
After typing a key it takes a short time before the letter is shown.

Expected Results:  
After typing a key the letter should be shown immediately, just how it was under ubuntu 14.04

Installed in Virtual box VM with:
- actual guest additions.
- 2048 MB ram
- 4 CPUs
- PAE/NX
- VT-x/AMD-V
- Nested Paging
- 128MB graphic memory

I have the same problem on Ubuntu 16.04. OS has been installed from the scratch. My laptop has ATI 6370M graphics. I suppose that graphics driver is the cause of such behaviour.

Also happens here with Debian 9 and an Radeon R9 M280X.
