demonstration database: see Form1
Starting in LO 220.127.116.11 (rc), when there is white text in a control button in a Base Form, where the button has a dark background, the text flickers. It almost looks like a bad refresh rate. However, I was able to capture a screenshot with the button text missing, indicating that this is actually an LO problem and not a graphics display issue. The flashing only occurs in Windows, and only with white text on a dark background.
In short, a fraction of the time, perhaps 1/8th of the time, the white colored text is missing and not rendered, and it is flashing in an unaesthetic way.
At the same time that this occurs, the menus are not populated with menu items. This is almost like a pegged-CPU, but my CPU utilization is normal when this occurs, 1-2%. This is very odd. Screenshot captured.
Windows 7 64-bit confirmed on LO 18.104.22.168.
NOT experienced when tested on Linux OpenSuse 13.3/KDE4.

screenshot of anomalous rendering of menus when form used
see what is missing from the dropdown menus when this bug is in action.

screen capture of button at time when text flashing off and not rendered
its a black box that is the button. This was like the sixth attempt to capture the flashing artifact. As you can see, the artifact is that the text completely disappears.

demonstration database : see Form1
this is the demonstration database. Open Form1. Obsoletes prior version.
this bug prevents the contents of the Base administrative window from populating, prevents the contents of dialog boxes from being seen, and prevents macro access to opening and drawing forms so that when you call a macro to open a new form the new form will open but it will hang before populating itself with data (experienced in split-database setup). In short, the bug is highly adverse should block production use of LO 5.0.0 in Windows 7 until fixed.
on retest, appears to be pegged CPU core caused by LO. Perhaps infinite loop or something similar. All text rendering including in Basic editor and dialog boxes blocked when form open with button that has white text on dark background.
Definitely blocks use of this version of LO.
Triggered by a background color on the control button of any color other than `(Default)`.

No flicker on OSX
I had to uninstall LO 22.214.171.124 because of repeated crashes of Windows Explorer on Windows 7 Professional 64-bit, which ceased when I rolled back to LO 126.96.36.199. The crashes occurred regardless of whether the LO application was open, but correlated to certain LO application actions like saves.

See properties, some missing and flicker looks as you described/ have shown - if I were you I'd try reinstallation of LO.
I uninstalled LO 188.8.131.52 (all LO) before newly installing LO 184.108.40.206RC3, thinking maybe it was something about special dev configuration. Not sure. Could also have been another branch of Bug 92110. In any event, fixed in LO 220.127.116.11 after reinstall. Based on feedback I'll call it INVALID.
