Hello! A few days ago I noticed a bug that made my kde lock screen crash and only come back a few minutes later, usually 10 to 15 minutes. This occurs when the lock screen is in "slideshow" mode and the folder (or folders) configured with the images has too many images. A similar bug occurs if the desktop is set to "slideshow" and the folder has too many wallpapers. In this case, what happens is that the system takes a long time to leave the presentation screen and go to the desktop. I do not know what the limit of wallpapers seems reasonable to the system, but the absurd amount I have (over 30 thousand) makes the system have this problem. When I used debian and kde was 5.12 I never noticed any of them, so it's probably something in kde 5.17, because even in 5.16, which I remember using in Manjaro, there weren't any of these problems
