Carla won't open Plugin GUI

Postby turboulli » Thu Nov 15, 2018 3:58 pm

Hello guys,

I am using carla-git with LinVst, running on Arch 64bit. Loading my win64 plugins (GSI VB3 and NI Kontakt) into carla works perfectly well, it produces sound and I am able to map the midi stuff. But when I am opening the GUI nothing happens and the carla log gives following ouput:


Code: Select all

Plugin refused to open its own UI
002a:fixme:x11drv:X11DRV_DestroyNotify window 0x2004e/2a00001 destroyed from the outside

NI Kontakt:

Code: Select all

Plugin refused to open its own UI
X Error of failed request:  BadWindow (invalid Window parameter)
  Major opcode of failed request:  18 (X_ChangeProperty)
  Resource id in failed request:  0x2c00005
  Serial number of failed request:  179
  Current serial number in output stream:  204

Altough the output is slightly different it is probably caused by the same problem.
I think xorg or wine could cause these problem but in ardour the GUI works perfectly fine, so my guess is that it is caused by carla.

Has anybody an idea what could cause this problem?

I'm having the same issue. Were you able to fix it?
I converted all my dlls to .so with LinVst (previously I was unable to open any dll in Carla). I have tested and most of them sound great but none will show the GUI when clicking on 'Show Custom GUI'. This makes it difficult to work with some plugin features.
