11.5 waveform rendering issues

[radiozombie]

hi all guys, marco from rome, italy

after updating to waveform free 11.5, it has to re-render the whole waveform after every cut, and i can't figure out how to solve this annoying problem.

i checked low detail interface, unchecked hi-res waveform, tried to switch the gui rendering mode from software to opengl, tried the experimental engine processing and the older one, but nothing, every cut in a track needs the waveform to be rendered again.

it worked like a charm before the upgrade, every waveform survived all the cut with the first render.
tips and suggestion welcome, thanks
