When painting quick strokes with my Wacom (Intuos 3) I experience some unwanted straight strokes (as if shift button was pressed in between) and after a few ones the pointer gets stuck on the brush circle and the full interface, except the canvas where I can keep painting, becomes unresponsive. Keyboard shortcuts seem to work. Some times pressing Alt button "revive" the app, otherwise I have to make AP windows inactive some way. Conditions for this to occur seem to be: There are plenty of layers in the document (or at least the more the easier) Tablet Input Method is set to High Precision The problem doesn't occur setting input method to Low Precision and Windows Ink. Affinity Photo 2.10 (and previous versions) on Windows 10. High Precision.mp4 .

I've came across this issue with the Pen Tool and stylus devices. If you try to draw straight lines with sharp nodes, very often you'll inadvertedly create smooth points instead. I've first noticed this on my Surface Pro 4, but I've also been able to replicate it on my desktop PC with very different hardware. At first I thought it was Windows Ink causing the issue since a similar bug was happening in previous versions, but switching to High Precision or Low Precision does not fix the issue. The 'trick' seems to be the rhythm at which you lay down the points? This is easier to replicate on the Surface Pro and it's pen, or at least it happens more often, seems like a somewhat fast laying down of points trigger this more often? On the desktop seems to be the opposite, slow and deliberate points seem to convert to smooth more often. I also got the feeling the longer the program runs, the more likely it is to trigger unwanted smooth points. Attached are videos showing the issue happening in both hardware / software combinations. There needs to be a higher 'dead zone' before sharp points transition to smooth points, otherwise it's a pain to deal with using the Pen Tool. Thanks! This first video is the Surface Pro 4 + Surface Pen + Windows Ink, while the second video is Desktop PC + Wacom Intuos + High Precision.
