Description Ricardo Bánffy 2021-02-25 16:59:14 UTC

SUMMARY

The top and bottom halfves of large parentheses, probably coming from the fallback font, show a misalignment issue. The spacing changes depending on which cells are selected or not. It doesn't affect all fonts.


STEPS TO REPRODUCE
1. Set the terminal to an affected font (my https://github.com/rbanffy/3270font is one)
2. Run Sage (`docker run -it sagemath/sagemath`)
3. Enter commands `%display unicode_art` and `diff(sin(x ** 2), x, 4)`
4. See the misalignment parentheses
5. Start selecting the bottom line. When selection goes over the '⋅', the spacing changes, changing the misalignments

OBSERVED RESULT
Characters are misaligned
Misalignment changes with selection

EXPECTED RESULT
Characters are aligned
Alignment doesn't change with selection
