Description:
Black boxes are covering random lines, so they aren't visible.  This sometimes goes away when scrolling but not always. This is what running in debug mode produces:

Jeroen@JsM4 Applications $ /Applications/MySQLWorkbench.app/Contents/MacOS/MySQLWorkbench --log-level=debug3
Logger set to level 'debug3'. '1111111'
2026-03-18 20:22:20.171 MySQLWorkbench[29929:812264] invalid icon for toolbar 
2026-03-18 20:22:20.662 MySQLWorkbench[29929:812264] invalid icon for toolbar 
2026-03-18 20:22:24.158 MySQLWorkbench[29929:812264] invalid icon for toolbar 

Really hoping for help!

How to repeat:
This happens anytime I use MySQL Workbench with a file that has more lines than the size of the screen it is rendered on

Suggested fix:
Remove the rendering bug
