+That makes sense. The GUI is likely more responsive because frame staging is now serialized with rendering:
+- The background goroutine no longer copies a large frame into Vulkan-mapped memory concurrently with GUI/render work.
+- StageFrame waits for the GPU fence before writing, removing CPU/GPU memory contention and undefined synchronization.
+- The bridge creates deterministic backpressure: the source cannot begin another frame until the current payload is staged.
+- The main thread now controls the complete render sequence instead of coordinating loosely through two channels.
+So we fixed both correctness and scheduling stability without adding another frame copy.
