Description:
Please apologize for my language, it's not my mother's one.
Bug occurs when i migrate to LO v6.3.2.2 (x64).
On some calc files, i have form buttons. Theses ones activate some BASIC macros.
On LO 6.2.7.1 and lower, no problem. On this last version, buttons flicker abnormally, like a persistant refreshing.
It will be a minor problem but the fact is that considerably slow down the use of that files (somewhat about 2 to 5 seconds to switch from one celle to another).

Steps to Reproduce:
1. open a file with some form buttons (buttons are colored, don't know if it's important) (i will try to join the file if i can)
2. show buttons flickering
3.

Actual Results:
form buttons flickering (with or without openGL)

Expected Results:
buttons that are not flickering ;-)


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes
