  • Estimated time set to 2:00 h
  • Affected version changed from 1.0.0 (B4) to 1.0.0 (B5)

Verified. Also found the problem to be bad whether the screen is Lowres, Hires, Laced, etc.
The problem is (at least in part) that the lines are not of uniform thickness.

I've seen the same problem where a box is drawn at the screen edges, but it is only visible part way across the the screen.

Also verified that this problem exists in both Amiga and AOZ manifests.
Here's an example in AOZ mode. I used a very small screen size to magnify and make the problem clear

#splashScreen:False
#displayWidth: 160
#displayHeight: 100

screen open 1,120,100,4,Lowres
Palette 0,$FFFFFF
Ink 1
cls 0

draw 61,10 to 81,10

wait key
end
