Ask someone who can empty QQ to teach me how to get rid of these white things. I can't read the diary or talk about it. I just want a pure background and a diary.

This gray thing belongs to one of the modular forms of yellow diamond, and there are many other modular forms, which are set differently. If you like the simple mode, you can set it to module splicing (the name may be slightly different, but it is the first one to set the module anyway) and then you can cancel all the objects (this step is very important, if you don't cancel, it should all be displayed, which is very complicated).
