Help! My brush is acting weird T.T
Hey guys, I am new to photoshop and I have just installed the latest version of it (22.4.2) for drawing purpose. I am using the very basic brush (hard round) provided by photoshop without changing any of the setting and the following image shows what comes out. Can somebody help me out with this?

The followings are what I'm using:
-Processor Intel(R) Core(TM) i5-10210U CPU @ 1.60GHz 2.11 GHz
-RAM 8.00 GB
-64-bit operating system
-Photoshop version 22.4.2
-Wacom Cintiq 16 Creative Pen Display 16.6x11.2inch tablet
