In my environment, it occurs even if USE_DIRTY_REGION_MANAGEMENT=OFF. This is probably due to the following code: https://github.com/flutter/engine/blob/main/shell/platform/embedder/embedder_surface_gl.cc#L91 `info.supports_partial_repaint` is always `true`.

@Kofhein Thank you for the information. I tried that, but it didn't solve the problem... @HidenoriMatsubayashi Sorry, I don't have any patches...
