I installed affinity photo on my windows 10 laptop. When i tested using my cintiq 13 hd the lines were slightly jittery.
I thought it was the same old problem because of windows drivers interfering, so i uninstalled my cintiq driver, and made sure to manually delete any remaining files and folders. I restarted, disabled windows input service (in system manager) and installed the latest driver. It's the standard thing to do when lines are jittery on photoshop.
When I started affinity and tried again, the lines were 10 times worse :-( I then freaked out and started photoshop but thankfully the lines there were still smooth and working fine.
Help please. I want to use affinity but the lines are making me cry
PS. I also turned off tip double-click distance in wacom preference. it helped a little but the lines aren't smooth.
