meters.lv2 crashes carla 2.2 #1297

Open dvzrv opened 3 years ago

dvzrv commented 3 years ago

Hi! On Arch Linux I'm experiencing crashes with carla 2.2 trying to open the GUI for any of the meters.lv2 plugins. The GUI roughly shows for about a second, then carla crashes.

This is what shows up in coredumpctl:
