Hi Dacap!
I’m working on v1.3.18-beta-x64. I have 640X480 canvas and when I use the new text tool and press enter to set it up the text moves left and part of it disappears.

I show the brush so you get the scale.
When I opened a new file with same dimensions and fonts it didn’t happen. When I went back to the file it was still present. I went out of Aseprite for a while and then back to the file. The problem was gone.
If I’m able to redo this bug I’ll inform more.
PS: I’m using windows 11 Laptop with remote through Windows 10 laptop. Steam version.
