I use Ubuntu-Studio 12.10 and here's my problem :
When I insert a plug-in on a track , I got a broken interface . I can use most of them without their respective interfaces , but most complex like EQ10Q are pain to use without its interface . The GUI is broken with all plug-in use in Ardour and packed with Ubuntu-Studio 12.10 . The real problem is that with former version of Ubuntu-Studio , plug-ins interfaces were working fine . I've tried Ubuntu-Studio 12.10 on different computers , and the same ! . But the most strange thing is that plug-ins GUI works with other plugin-host softwares like LV2-Rack . Here's screen-shots of the same plug-in but run in different hosts :
I don't know if it's a problem of dependencies or settings , but I hope that someone in the Ubuntu community knows the solution !
Thanks by advance !
