Sorry for just dropping a log line here, but I don't have much technical details at hand. Sometimes, often when trying to open the custom GUI of some plugins (which sometimes work OK, sometimes not), such as LSP Mixer x8, or Drops, Carla just crashes and the log reports [carla] Carla assertion failure: newFrames > 0 in file CarlaEngineInternal.cpp, line 260. I'm using Carla 2.5.7 release from Fedora package Carla-2.5.7-1.fc38.x86_64 , using Fedora 38.

I've had Carla and VST plugins working better using x11 instead of default wayland, starting carla via terminal with GDK_BACKEND=x11 carla.

Crashes still, but i have tried x11 natively and it doesn't crash there.

Same here. Crashes on wayland, works on x11. For me a wine-bridged windows vst crashes. The plugin complains, that the audio engine isn't running. When I set QT_QPA_PLATFORM=xcb, as proposed in #1527 , it doesn't crash, which is nice :) Anyway, when I try to capture the window in OBS I can't see it. What's going on?

Same issue here, doesn't works on x11 for me. When I set QT_QPA_PLATFORM=xcb it crash again. Uncomment wayland in custom.conf doesn't change anything. carla version 2.5.8 Ubuntu 22.04 LTS
