I have noticed that after I installed a font bundle I purchased (http://www.kimberlygeswein.com/), Affinity Designer in Windows 1.8.5.5703 started freezing on color selection (dragging the full color spectrum selector) and just creating rectangles and such. The app will slow down or freeze and then draw the rectangles or allow to change the color. I immediately removed all the fonts I installed, and the problem went away. I have a intel i7 10700K with 32GB ram, M.2 1TB SSD main HD and AMD 5700XT GPU.
sigmb6 got a reaction from GRAFKOM in Designer 1.8.5.703 freezes or slows down when Windows has a lot of fonts
