ACR 8.6 is now the current ACR version how does that work. Using ACR 8.6 as a filter on my windows system on a large document viewed at 100% I can set the Brush inner solid circle larger then my 1080 screen height.
Photoshop CC 2014 brush size can be larger then screen size. Make sure you have the latest device drivers for you display adapter.
Thanks for the reply. I have updated Camera Raw to 8.6 and I can increase the brush circle as big as I want but the brush circle sign will disappear when the brush size above 700 px on Photoshop and adjustment brush size above 12 on Camera Raw 8.6, instead I can only see the arrow sign on the screen if I keep enlarge the brush size above the mentioned range.
