Main window is sluggish and unresponsive when being moved or resized

When the FRV main window is moved (via dragging, or by window managers), it takes 2-3 seconds to start moving. Once the move is finished, the GUI is completely unresponsive for another 2-3 seconds before I can interact with it again. It gets quite annoying since I use a tiling window manager that moves windows around.
Something I noticed is that when resizing a window, the issue only happens when resizing from the top or left edges of the window. Resizing from the right or bottom edges doesn't cause the GUI to become unresponsive.
I've tried both OpenGL and DirectX11 engines.
