Memory leak when switching wallpapers with DPM off

[xiaohuirong]

I have a script that switches wallpapers on schedule. After turning off the monitor power using a tool dpms-off based on the zwlr_output_power_manager_v1 protocol, I noticed that the memory usage of swww-daemon gradually increases with each wallpaper switch. I tried #375, but it doesn't seem to work.

Based on my testing, it appears that memory leaks occur due to unsuccessful (in case of dpms-off) or overlapping transitions. As temporary fix you could use --transition-type none or kill swww-daemon before and start it after dpms-off.
