It is necessary to draw a moving ball on the QImage. In order to realize this function, I frequently redraw the PNG image on the canvas, which will report insufficient resources. Is there a solution?
1.Error loading pictures
2.Redraw the background every 0.1 seconds,Draw another moving ball -

About how much (free) memory does your machine have? Do you get an error message which you can paste here? Can you produce a few lines of code which show this error?What does '4k' mean? 4000x2000 pixel? If so you need at least 400020004bytes = 32MB of free, contiguous memory.
As @JonB already said - please show use your loading and displaying code.
Also it's not a good idea to load an image every 0.1 second.
