Ok, here I have listed all the bugs I have experienced with Photoshop using a Wacom in Windows ever since Photoshop switched to WinInk. These bugs have been apparent for multiple years and I have them on all my PC's using a tablet display and on multiple installs of Photoshop, so they are not unique incidents. I hope Adobe can troubleshoot these and iron out the last bugs of WinInk once and for all.
-"Esc" button doesnt work when doing polygonal lasso 90% of the times.
-Canvas scrub/pan using space while doing Polygonal Lasso does not work 90% of the time
-Moving a layer in small increments using the Move tool is buggy. The layer snaps back into its original position. you need to use your mouse or move with arrow on the keyboard. This is even if all snapping is turned off. This also includes moving points on a spline in small increments.
-Using scrub zoom with a mouse when you have Photoshop on a second monitor and tablet often bugs. Meaning it will not zoom and the entire image just jitters. Once using the tablet, it works again and most likely tyhe mouse will work too.
-Crop tool expanding the image with a mouse also bugs a lot and do weird large expands or refuse to let you crop with a mouse when you are using a tablet.
