I would like to report a smaller "bug" or peculiarity.

I don't know if this has been addressed earlier, I didn't find it with a search. The problem is as follows:

Whenever Total commander is opened, full screen dosbox starts "laggin" but only, when something happens on the screen which has an effect on the whole screen.

I know it sounds weird, but let me explain with an exemple: I startup quake, duke, shadow w, blood...any game. Runs fine, until I pick up something (you know when you pick up something the whole screen lights up for a sec) and then it starts to move slowly. The problem is reproduceable, and also present when there is a whole screen fade in or fade out (in an intro for ex.).

This issue only occurs, when running dosbox full-screen and Total commander is running in the background.

After exiting totalcommander, everything runs fine, so it's not a tragedy, I just wanted to ask you guys if anyone experinced something similar?
