What I mean by this is:  Deepin can handle almost any resolution as a desktop background/wallpaper even Apple's 6016 × 6016.  However, the lock screen -- particularly on startup -- seems to be unable to handle anything beyond 3000 × 2000. Is there a workaround here? Or is the lock screen hardcoded with a maximum resolution? If so, I would hope/recommend that this be changed to handle anything up to 6016 × 6016 as 4K and 5K screens are becoming more and commonplace!
