Research direction
Investigate the Wayland event loop in egui to understand why request repaint is not triggering an update when the window is minimized. Look at the referenced PRs (#7422, #5112, #5113) for context. The issue may require coordinating with the assignee to ensure the fix covers the minimized state appropriately.
