            Bug ID: 118381
           Summary: Inaccurate symbol signs
           Product: LibreOffice
           Version: 6.2.0.0.alpha0+ Master
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: trivial
          Priority: medium
         Component: UI
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: thorsten.wagner.4 at gmail.com

Description:
Visualization of symbols, e.g. plus sign, up arrow, down arrow, is inaccurate
probably due to roundig issues between drawing coordinates and physical device
coordinates.

A prominent example is the asymmetric plus sign for adding new sheets in Calc,
but issue is present on other symbols too.

Steps to Reproduce:
1. Open an empty Calc sheet
2. Look at the plus sign on top of the status bar

Actual Results:
Inaccurate representation of symbols:

Screenshot 1: Asymmetric plus sign using macOS
Screenshot 2: Asymmetric plus sign using Linux (GTK)
Screenshot 3: Inaccurate left arrow using Linux (GTK)

Expected Results:
Accurate, especially symmetric visualization of symmetric symbols:

Screenshot 3: Reworked visualization of plus sign
Screenshot 5: Reworked visualization of left arrow


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes

Additional Info:
Issue is independed of using Open GL.

I'm preparing a patch to fix the issue and will upload it to Gerrit in brief.
Screenshot 3 and screenshot 5 are taken with patch applyed. I'm testing on
macOS with and without retina display and on Linux as well.
