            Bug ID: 142061
           Summary: Calc UI: Display anomalies when resizing columns (Mac
                    Catalina)
           Product: LibreOffice
           Version: 7.1.2.2 release
          Hardware: All
                OS: Mac OS X (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: pfatula at uchicago.edu

Description:
In Calc, when I resize a column (click on the divider between columns and drag
to change its width), there are some significant display anomalies, even before
I start to drag. This started (I think) with version 7.0, and persists in
7.1.2.2. Mac Catalina. It happens every time I resize any column in any
spreadsheet. 

The bug happens even if I create a new account on my Mac and run LibreOffice
from that new account, with default settings in OS & LO.

See this discussion, which includes a screenshot.

Steps to Reproduce:
1.Click & hold on the line seperating two columns of data
2.The problem appears immediately
3.Move your mouse around it gets worse.
4.When you let go of the mouse button the columns have been resized and things
look normal again.

Actual Results:
Display anomalies appear when attempting to drag to resize columns

Expected Results:
The columns should resize as you drag, without obscuring the contents of any of
the columns.


Reproducible: Always


User Profile Reset: No
