Scrolling and multitasking lagging since updated to iOS 10

Hello,

My iPad Pro 9.7" scrolled smoothly and multitasking was snappy on iOS 9.3.5 but since updating to iOS 10 it lags when scrolling, especially when using slide over. ( I.e scrolling app picker or a website in Safari is visibly very glitchy) Just to clarify I don't mean a little bit slower I mean visibly horrible.

Also opening notes app in split view for example, it takes a while to load the note the first time even though it was instant in iOS 9.

Has anyone else experienced this? I did a reset all settings and I'm hoping not to have to do a clean install.

Thanks
