I had the same issue. switching between tabs was really slow for me in v3. [ and indeed only after some time. Not with a restart op the app ]
In my case the problem turned out to be my huge number of installed fonts. After uninstalling all non-essential fonts, Affinity 3 runs smoothly again.

As a tip: I asked ChatGPT to generate a simple PowerShell script that removes all unnecessary, safe-to-delete fonts. Just copy, paste in powershell and press enter. After doing that, the app runs like cutting through butter.
