[Konsole-devel] bugfix/speedup

[Paul Pogonyshev]

Hi, Konsole team!

Thank you for the nice program that i use a good slice of my computer time ;)
I wrote once about Konsole being too slow at redrawing (e.g. when scrolling)
but you all seem to be using it with transparent backround which has been ok
regarding speed.

This simple patch speeds redrawing up noticeably (with solid or texture
background) and almost eliminates flickering.

Please let me know if i missed something or if it doesn't work under some
circumstances.

best regards,
  Paul Pogonyshev
