Hello Affinity,
I'm using your software since version 1.6.5 and a month ago I've built a new PC (Specs below)
The problem is that Affinity Designer (I don't use Photo much) is operating very slow with a medium amount of object and even freezes sometimes.
At first I thought it was a bug of the version 1.10 so I deleted it and installed the previous one but the problem persisted.
First problem: when tracing a shape with the pencil tool sometimes it kinda delayes even if the document has only three objects.
You said Affinity Designer will be able to handle up to 600,000 objects with no lag but I have extreme lags even with much less amount of objects (check the wool.afd file). Even when I rasterized everything it still lagged.
