ADDITIONAL INFORMATION

Comment 1 José Otero 2020-03-29 01:20:41 UTC

Well, just reading my comment here for reporting the bug. I am realizing that it very well may not be a issue of KDevelope. But an issue of my system in general.

I see my comment, in my browser Falkon 3.1.0, and the lines where the symbols appear are shown pushed down. It is like these symbols (in my system) had an additional height, and needed more space in the line. So, when inserted they push the whole line down.

I appologize in advance in case I am reporting a non-issue.

This bug is in the KTextEditor component, but it is kind of there. It doesn't deal well with oversized (in height) characters, since IIRC it is built around having constant line heights.
