Chrome and Safari Causing brush malfunction in Photoshop
Whenever I have my cintiq plugged in and i am using chrome or safari and then switch to using photoshop and try to use the brush or eraser tool, something happens and i can only make dots and straight lines with those tools. other tools appear to be unaffected. this lasts for about 30 seconds before going back to normal. the only way i've been able to get around this is by clicking on another program between using a browser and using photoshop. If i do this the issue does not occur. It also does not happen when i don't have a tablet plugged in. the issue is exactly the same in cs6 and cc and with safari and chrome. I haven't found any other programs that cause it but i don't have any other browsers on my computer right now.
Im using a macbook pro with retina 2013 13 in" running high sierra.
Any advice is greatly appreciated, thanks.
