[linux-audio-user] Slow repaint in FST / Wine

[Jean-Baptiste Mestelan]

Hello list :-)

I've just reported success using FXpansion Guru (VST drum machine) through fst .
http://ladspavst.linuxaudio.org/

One minor inconvenience, though, is that the visual timeline does not
move in sync with the beat  ; I suppose this is due to the window
repainting very slowly, as can be noticed if I switch focus to an
other workspace, then focus again to Guru.

My question is : what factors do, in your experience,  affect repaint
speed? Is there anything that I could do to improve this ? It does not
seem to depend on the window manager (I've tried XFCE and Ion3, which
makes no difference).

Thanks for suggestions :-)

NB1 : VST sux and all, I know, I know ....
NB2 : Funnily, the plugin also works through dssi-vst, but then, no
visual timeline is displayed at all.
