The issue stemmed from the `is_dirty` flag not being cleared without render callbacks during lock. The release also expands wallpaper storage capacity to 500 images, adds support for adding multiple wallpapers at once, and includes fixes for the frosted glass theme, including a bug affecting applets on hotplugged external monitors. ## Full article daily.dev links to this article rather than hosting it.
