            Bug ID: 139950
           Summary: MAC OS 11 Big Sur - Window content not correctly
                    refreshing in Write and Impress
           Product: LibreOffice
           Version: 7.0.4.2 release
          Hardware: All
                OS: Mac OS X (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: LibreOffice
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: florent.kieffer at free.fr

Description:
Bug appeared with Mac Os Big Sur (had no problem on the same computer with
older OS)
Glitches found in Write AND Impress but are not exactly the same.
Write and impress :
the text position cursor is blinking weirdly (too fast)
text selection is not visible.
sometimes, button pictures are not correctly displayed.

Impress : text is not displayed when typing in a text zone. Only displayed if I
resize the whole window, or move the text box.

Write : opening a recent file from startcenter : buttons (top) and navigator
appear in the window, but i can still (partially) see the startcenter interface
(kind of a background picture masking the document), just in the part of the
screen where the content of the document should be loaded.
The document will only be displayed if I resize the window.

Steps to Reproduce:
1. Open / create document with text in write or impress
2. type text
3. select it

Actual Results:
In Write : newly typed text does not appear.
Selection not visible. Cursor (vertical line) is blinking incredibly fast. 

Expected Results:
Text should appear in real time.
Selected text should be visible.


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes

Additional Info:
The problem happens every time i'm using LibreOffice with my computer. Yet, on
the same machine BUT another user account (OS account), I could not reproduce
it.
