Bug in freetype.dll?

[Hartmut Birr]

Hi,
sometimes I see a debug messages like this:
(mm/npool.c:1641) Trying to allocate 254736304 bytes from nonpaged pool -
nothing suitable found, returning NULL  (objects/text.c:1832) WARNING:
Failed to render glyph!
If this occurs the desktop background is flashing white. The big allocation
request comes from freetype\src\raster\ftrend1.c line #178. Has anyone an
idea what is wrong?

Hi,
I get the behavior (described in my last mail) always if I move the cursor
about one of the buttons in the button bar (icons right from the start
button). Has anyone an idea what is wrong?

My guess (not more than a guess at this point) is that this happens when a
tooltip is displayed. It could be that the font for the tooltip is a huge
size (and I mean HUGE). That would explain the flashing (tooltip is
displayed and removed) and the memory allocation.

Hi,
I've added a line 'DbgPrint("%d %d %d %d\n", cbox.xMin, cbox.yMin,
cbox.xMax, cbox.yMax);' in ftrend1.c in function ft_raster1_render after the
line where the cbox values are set. I get '86272 0 2815808 3057600' for the
flashing window. All other prints from this point are '0 0 640 384', '0 0
320 448' or '0 -128 384 384'. The values are in a range from -128 to 640.

Cause was a failed call to SystemParametersInfo. Fixed now
