I have attached two videos:
i) High CPU tabbing - I paused clicking through the tabs to show that you really do have to click all of them. Each tab is consuming like 10% cpu until it gets focus.
ii) Steps to replicate - this one I launch affinity and load 10 copies of the attached afdesign file. Affinity pegs the cpu as soon as I select something. This is 100% replicable.
a) it seems to happen on focus changes e.g. app switching, virtual desktop switching etc. as soon as affinity gets focus - boom - it's off until you focus each tab.
b) I also notice that when I focus a tab, affinity often pans zoomed in documents to a corner. It may be a separate bug but it's part of the oddities happening when affinity gets focus.
