Editor display broken

I have 1.8.12 (which says it is Windows Store 1.8.33), and it has serious display problems. I find wide whitespace which does not actually exist in the file; if I try to delete the space, the characters preceding it are erased, meaning it isn’t actually there at all. Now it has taken to displaying characters on top of each other. I exited it and restarted it, and the problem still exists, as shown in the attached screenshot. If I look at the same files with NotePad++, I get the correct information displayed, as shown in the other two screenshots. I could send lots of other examples, but these are pretty bad.

Not 100% sure if THIS is the same issue ?

You could of course also report it HERE

Thanks Per for the heads up.
