Hello,
I am new to Affinity, so I am sorry if it's my fault. When i tried making pixel art with symmetry turned on and width of the pixel tool was an even number, symmetry mode became inconsistent, it started adding more pixels to one side and doing some weird shapes. It happens everytime.
I have Windows 10, version 1909 and build 18363.836
Sorry for my english, I speak czech
