Description:
I have noticed this problem when did a formula screenshot. At increase in scale more than 200% the scalable brace in a formula disappears, isn't displayed on the screen. It happens both to a single bracket and to a pair bracket.

Steps to Reproduce:
1. Insert a formula into the Libreoffice Writer document.
2. Use a scalable brace in a formula.
3. Increase scale more than 200%.

Actual Results:
The brace isn't displayed on the screen.

Expected Results:

Reproducible: Always


User Profile Reset: Yes

I can't reproduce it in KDE and Windows. Only on my laptop. What information about software will help to solve this problem?

I think, a problem in the hardware or drivers of graphics.

Does it work if you disable OpenGl ? -> https://wiki.documentfoundation.org/OpenGL

I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' if the issue is still present

No need to ask as OpenGL was not used: Отрисовка ИП: по умолчанию;

Hello alexch82,
A new major release of LibreOffice is available since this bug was reported.
Could you please try to reproduce it with the latest version of LibreOffice
from https://www.libreoffice.org/download/libreoffice-fresh/ ?
