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 SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Ubuntu 20.10 (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: 5.14.2 ADDITIONAL INFORMATION
