Affinity v1 issue with Pixel Persona

[Santa]

I'm enjoying the Pixel Persona environment and decided to do some pixel art. It's been going well for a few weeks, however my computer crashed last night and now my pixel won't be a normal pixel anymore. I draw mostly with 1 and 2 px, and 1px works good still, but 2px is somehow slightly rotated and draws 4px blocks instead. I cannot capture my mouse icon, which should be a normal square but is now slightly rotated. I haven't figured out how to return this square back to normal.

The grid is set to 2px, the width of the pixel is 2px as well (and yes, enjoy the Christmas art I've made so far) -- yet the block is 2px plus some 'bleeding' because the square is rotated. When doing 1px, it's back to normal (probably because too small).

Check the brush rotation and use modifier keys to unrotate.

or create a fresh square brush.

Modifier keys

When using the Paint Brush Tool, the following modifier keys can be used:

• To draw a straight brush stroke, lay down your initial stroke, then -click at the position where your stroke is to end; keep the key pressed to continue the straight line stroke.
• To constrain a stroke to the X-axis or Y-axis, press the   immediately after your initial stroke is laid down, then drag along the X or Y axis to the position where your stroke is to end; keep the key pressed to continue the stroke.
• Hold the   and press the left mouse button to pick up a new color under the brush to paint with.
• To decrease or increase brush width, use the [ or ] s, respectively.
• Press the  and  s together and:
  • Click to cycle between width and hardness, shape and spacing, and rotation attributes.
  • Drag left/right or up/down to adjust the corresponding attribute. For example, with width and hardness attributes selected, drag left/right to adjust the first attribute and up/down to adjust the second attribute.
• With many brush tools in Pixel Persona, you can quickly change the opacity of your brush using your keyboard's number keys.
• To change flow instead, hold the   and press a number key.

Preferences

It appears that the OP is using the Pixel Tool (note the icon in the Tools panel in the screenshot), not the Paint Brush tool. So I think the solution is to click on the More item in the context toolbar & reset the Rotation: value to 0% there.

Did you test on your own? 
at least on iPad all brush modifiers for paint  brush are active for pixel brush. So having the wrong modifiers active by accident you can rotate a square pixel brush perfectly explaining the issue.

Rotation was set to 1% apparently, no idea what the shortcut is or how it even got edited, since I've never used settings anything other than the pixel size. But merci, it's now fixed!

Yes, I tested in Affinity Designer's Pixel Persona in the desktop V1 version. Note from the OP's screenshot it is the V1 desktop version & that tool in the Pixel Persona.

Not sure why you are showing AP or the iPad version.
