Rack 2.20 Linux shows blank plugin window with Bitwig

Hello, after updating from 2.12 to 2.20 the Linux Plugin doesnt work anymore with Bitwig on Ubuntu Studio. ( see screenshot). It shows just a black window.

I tested on two almost identical machines in terms of operating system (Ubuntu Studio 20.04), both with nvidia gfx cards. Downgrading to 2.12 works though. Any idea would be helpful.

Also, the VST3 Version doesnt show up, neither when located in .vst nor .vst3 directory

Thank you.

Btw I checked in Carla and VCV and same there.

Can I assume you are using Wayland?

I think its still X11 , since ist quite old. but I am not really shure and honestly dont know how to check this.

And in Standalone Mode it works as before.

Run echo $XDG_SESSION_TYPE in a terminal.

Thx, its still X11

Got an answer from the devs :

" This is a known bug and we are hoping to fix it soon."

So let’s be patient :wink:
