The mini-patch resolves the canvas not appearing. Though, not enough.
The ruler may not appear or disappear as intended pressing ctrl-r. This is the case with AMD graphics. Unsure about Intel or NVIDIA graphics. No issue with ElementalWarrior's affinity-photo3-wine9.13-part3 branch. The ruler appears or disappears upon pressing ctrl-r, depending on the state.
