            Bug ID: 114580
           Summary: Screen Font Antialiasing Causes performance problems
                    and needs to be retoggled with each restart
           Product: LibreOffice
           Version: 5.4.3.2 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: udgrafdes at yahoo.com

Two (possibly related) problems. I'm unable to determine actually which state
the screen font anti-aliasing is in due to it, as well.

First off, screen font antialiasing causes performance problems. In calc, it
takes multiple seconds after I enter anything in a cell before it displays.
This seems to be corrected when I toggle screen font antialiasing in
Tools->Options->Libreoffice->View

When I restart the program, the actual state appears to be reset, but the
checkbox itself is not (it remains in whatever state I last had it). So I
cannot even tell if antialiasing is enabled or disabled to get the performance
problems.

This problem occurs whether or not I toggle hardware acceleration, opengl, or
"use antialiasing" on the right side of this menu.

In face, I'm not sure what the practical difference between "screen font
antialiasing" and "use antialiasing", as the tooltip simply says "restart
required" for the latter, and the former has no tooltip. Is the latter for the
interface? The former seems reasonably self-explanatory, though.
