win 0.4.8 resonance artifact -please test

Having trouble with LMMS? Ask about it here.
Would someone that has dl the new release 0.4.8 try this:

Add a default kicker plugin
On the FX-tab add LADSPA vintage-delay
Open the effect-controls
Add 'Amount' 0.64
Play default C5 on the Preset piano
A severe artifact occur

Can this be confirmed?

This I believe is the origin for the artifacts in automation tracks where LADSPA vintage-delay has been used. -sound like clipping?

-Also try playing higher notes (c4..c3) -On my pc the sound disapears completely (al instruments) and can only be restored by disableling the vintage-delay or removeming the effect.
yes, your right.
Also found a weird problem when trying to edit an automation eg. volume setting, every mouse movement is drawn on the screen. only out is to shut down and reboot the program.

Thanks pete for confirming this.
I have now made a video and this also show a 'solution' for the milder artifact behavior, but this is a bad problem!
I have submitted a ticket for the dev-team
