Crash with multiple custom GUIs #900

Closed BlueMax closed 5 years ago

BlueMax commented 5 years ago

When i have two custom GUIs open from 'Robin Gareus' plugins (e.g. 'UV meters') they run for 10-30secs and then crash/freeze Carla (no screen/window updates, sound continues properly). This also happens when i add/remove/add one of these plugin. This doesn't happen if i 'replace' the plugin. It works properly if i just add one plugin and keep it. Other plugins seem to work fine.

The bug itself seems to be xorg or nouveau related. Sometimes just the Carla window freezes, sometimes the whole graphic backend/keyboard is frozen. I can always SSH into the machine and kill Carla though to get the system back.

Anyone having the same issue?

Never mind. Looks like Nouveau is the culprit here. https://github.com/x42/meters.lv2/issues/25#issuecomment-511513553
