Logic Pro 11.2.2
macOS 15.6
Dual monitors (3360x1890 and 1920 x 1080, bug occurs with either one)
Neutron 5.1.0
I updated Neutron 5.0 to 5.1 today through Native Access. Here is how to replicate the GUI bug. Open Neutron. Resize the GUI by dragging the bottom right corner. Close Neutron. Now, reopen Neutron. See screen pic below.
