I'm trying to get some illustration done on my tablet in Affinity Photo, which requires quick response from the application, so I can get nice smooth lines with the pressure settings. The current version 1.8.0.585 has a delay when assessing line pressure and causes a lag effect that impedes my judgement when drawing lines. - Is there some way I can go back to the previous version where this wasn't an issue?

I'm having the exact same issue on PC. I tried clearing everything from the application. Changing the performance settings and quality, but it still lags.
