In Affinity Photo the swatches panel lags quite a bit, while the swatches panel in Designer is fine. This is especially apparent when browsing large swatch sets, such as Pantone. See here:

Both apps are using the same Performance settings:
Its great to see that Serif still appreciates the value of Pantone in 2022.
The color picker swatch panel unfortunately is super slow, clunking as you try and scroll it and impacts the side panel/s and window resize performance dramatically. small swatch sets do not create the problem.
Each swatch is an object i guess, with hundreds of objects being moved the team did not optimise.
