Git commit 92b5ca8cda216c1109d4c57e6a2159262c235cb2 by Fushan Wen. Committed on 24/09/2021 at 16:19. Pushed by ngraham into branch 'master'. Fix "Now Playing" view's background flickering Prevent dynamic binding of sourceSize which causes the background image to be reloaded frequently when the display size is changing. To limit the memory usage of the background, set sourceSize to a fixed value when the original size of the background is very large.
