If you're a nvidia gsync user and experiencing mouse stuttering in Ps (and all Adobe apps), try turning off gsync to see if that resolves the issue. Basically what happens is that any activity in an Adobe app will result in 2-3 seconds of micro-cursor stuttering (looks like frame rate dropping) and the occasional 3-4 seconds of cursor freeze. Disabling gsync fixes the issue. This behavior appears only in Adobe apps and none other.

Hello, IIRC, in the past some customers reported fixing some display issues by deactivating G-Sync in their drivers. I would also try to check "Deactivate Native Canvas" in the menu Edit/Preferences/Technology preview (Pc) or Photoshop/Preferences/Technology preview (Mac) . This is not a fix, but rather a way to check if the issue appears only with the new technology, and should be reported to the Ps team.
