I have tried every solution in this community
and nothing works for me (sprk 200 seems to work but it was not solution for lagging when using Alt key)
everytime using Alt + Click (colorpicker) it causes lag and delay makes dot on canvas
I had this problem before and at that time i fixed with " # Use WinTab UseSystemStylus 0 Windows" and turned windowsink off, but this time it doensn't work at all and nothing works for this issue
sorry for watermark in video
please fix this issue asap Adobe
