Description troodon 2009-08-17 22:06:33 UTC 
At some zoom levels the bars of the equal symbol from OpenSymbol v 1.21 are
rendered with different thickness.

This happens in all applications, no matter if subpixel rendering is on or off.
I've tested with OOo (Calc, Math, Writer) and with Word 2000.

Older versions of the font had this issue too, which has been reported many times:

Seems to be a bit better than before, but I still see the bad rendering in the
testcase at the following zoom levels (Windows Vista, 1280x800, subpixel
rendering on):

147%-153%
248%-253%
348%-353%
448%-453%
548%-553%
648%-653%

And so on :-)

Tested with OOo 2.4 (Windows XP) and OOo 3.1 (Windows Vista) and the v2.3 font 
looks great. So this issue seems to be fixed :-)

Thank you!
