Not sure if this is a hardware issue or a software issue. I find that when I open filter gallery and I often have the same 4 filters pre-loaded (3 grains and a stamp) the preview image takes around 20 seconds to fully form. It just loads very slowly block by block. Document size when this happens is always 7020px x 9930px at 300dpi.
My PC is no slouch (12th gen. Core i7, 32GB RAM, RTX3070)
Does anyone have any ideas? Thanks in advance 😊
