Bug 107909

Description:
Text disappears and reappears depending on zoomlevel and cursor placement
Text is visible at zoomlevel 100%; but invisible with 90% or 110%; but not if the text is bold.

And it isn't just the zoomlevel. If the cursor is placed in a textbox, the text within the textbox gets visible at zoomlevel 100, but not the text outside. 



Steps to Reproduce:
1. Open a writer document
2. Type something (for example: ...............)
3. Play with the zoomlevel

Actual Results:  
Text can disappear 

Expected Results:
Text should always be visible


Reproducible: Always

User Profile Reset: No
