The latest patch also fixes offsets and other GUI issues for LMMS VSTs through Vestige.
To clarify, the patch only fixes the LMMS VST offsets if the GUI is not moved and left in the original opening position. Moving the VST windows out of its original position still introduces the GUI offset mouse misalignment.
It seems that either yabridge or wrapper apps like Carla call windowing updates to track window movement that works with the patch but not LMMS.
