Worked on the LMMS/lmms repository to address a GUI stability issue affecting the Carla Instrument plugin on Wayland systems. Focused on bug fixing and GUI development using C++, the work involved reordering two function calls within the InstrumentTrackWindow to ensure proper initialization before updating the instrument view. This targeted adjustment reduced Wayland-specific GUI breakages and improved cross-platform reliability for plugin users. The process included careful debugging, code modification, and validation across multiple Wayland sessions to prevent regressions. No new features were added during this period, with efforts concentrated on enhancing user experience and maintaining code stability in the plugin environment.
