Photoshop 2019: Clone stamp lag with in Photoshop with Windows 10 and Wacom tablet
With the 2019 update, Photoshop seems to lag badly with Clone Stamp on Windows 10 64-bit, using a Wacom Tablet (Intuos Pro L with Pro Pen).
Lag is possibly not quite the right term... it kind of does a spot as you click but then as you drag the pen no more cloning happens. You can do another spot by tapping again but drag gives you no more 'ink'. Doesn't happen immediately - takes a minute or so usually to occur.
Weirdly alt-tabbing away and back completely clears it, for a while at least.
Looking at task manager, it doesn't look like it's using the CPU (roughly 10%) or GPU (up to 20%) particularly intensively.
It does not appear to be the same thing our Mac users are experiencing, which is the issue documented elsewhere on here, which is cleared by hiding the rulers.
Using the latest version of PS (20.0.0), Windows 10 Pro x64 build 1803, Nvidia 416.81 driver; system spec - GTX 1060 6GB; 32GB RAM, Intel i7 6700.
