Specifically, their mirror images are the middle of the pixel, not the middle of the grid. Minecraft textures are 2x2 in size, so if I click on the left side of the panel, only one pixel shows because the middle part of the supposed symmetry is a pixel not the grid. If the mirror was grid based rather than pixels, it will paint on both sides.
I can't seem to find the settings for this, Should I download a plugin or use a different program entirely, still the same case on krita.
