Error lv2 in Carla with Debian 12

lv2 and vst/3 not openin GUI in Carla with debian 12

[devloop0123]

They probably open a 1x1 window. I have the same issue with the vst2 in MusE. The lv2 version opens a somewhat larger window which I can easily drag larger.

Hello !

I have the same issue : 1x1 pixel GUI, with VST2 version.
I'm using linux, I tried both Ardour and Carla.

If I manage to get the mouse on the right pixel, then I can trigger a resize event and the GUI appears.
