I run Ubuntu 9.04 with the Gnome environment by default. Recently I've started playing around with Kdenlive, a KDE application. I've noticed a number of graphical glitches in it and am wondering how many of those glitches may be due to running a KDE app in a Gnome environment.
Are there any implications to running a KDE app in a Gnome environment, or vice-versa? I'm interested in reliability in particular, but also things like any significant performance concerns or what-have-you.
