08:24 zzag: emersion: do you use shm or dmabuf buffers for wallpapers?
08:25 zzag: in plasma, I know that if you have a couple of 4k monitors, the memory usage can increase and fixing it is hard :(
08:25 zzag: we use dmabuf
08:25 zzag: and desktop windows can have different contents
08:25 zzag: and there can be multiple buffers allocated for a single desktop window, etc
08:36 emersion: zzag: shm but with a trick to destroy the buffer after commit so that the compositor can release the shm memory
08:37 emersion: the compositor still holds onto the GPU memory
