Studying the dynamic behavior of topological spin textures can unlock future low-energy and high-speed spintronics devices. Recently, synchrotron-based technique diffractive ferromagnetic resonance (DFMR) was developed, allowing for element-selective studies selected, ordered magnetic modes. In this work, authors reveal by using DFMR how time-dependent magnetization dynamics couple to complex texture in well-known chiral system Cu${}_{2}$OSeO${}_{3}$, uncovering dynamical phase compressing that remained previously hidden other experimental techniques.
