LMMS linux: vst setting through wheel buttons

Having trouble with LMMS? Ask about it here.
When I try to change a parameter by the wheel of any vst (for example synth1, glitch), just click the pointer of the mouse appears displaced at the top of the corner. It occurs with any "wheel button".
Lmms works on Debian.
I'm not sure if I understood that... can you elaborate?
I have had similar problems with some VSTs (not all though!). Basically when you click and drag on a VST's button, even a minuscule change causes the mouse cursor to jump on the edge of the screen. I thought that it's Wine problem (I'm in Linux), but it might be something else.
I thought it may be wine configuration problem.
I'll try to exectue them with vsthost to check if the same problem persists...
Thanks!
Oh, the synth1 thing, now I know what you mean.

Yeah, it's a wine thing... it's because of certain architectural differences, IIRC something to do with coordinates... it's the same thing why all popup menus show up in the wrong places under wine. It's probably not going to get fixed anytime soon.
