This is not X11 related. If you load the attached .lyx file, you wont
be able to see the second \Omega, and the first one is displayed
in black. When setting USE_PIXMAP_CACHE to 0, the second \Omega is
visible again, but they are in black, still. Happens with Qt 4.1.5,
4.2.2, 4.3.0, and 4.3.1.
Got it I think. The problem is that \Omega use the character 173 in the
cmr font. 173 == 0x00ad, does that rings a bell?
Here is the relevant code in QLPainter::text:
// Qt4 does not display a glyph whose codepoint is the
// same as that of a soft-hyphen (0x00ad), unless it
// occurs at a line-break. As a kludge, we force Qt to
// render this glyph using a one-column line.
if (s.size() == 1 && str[0].unicode() == 0x00ad) {
This code happens before we chose or not to use the pixmap cache so I
don't really understand why the non cache case is not affected. I'll
include the font family in the test above and report back if it fixes
the problem.
Question: was this kludge introduced exactly for the purpose of
displaying \Omega?
Abdel.
