Setting OSG_TEXT_INCREMENTAL_SUBLOADING to off does not make a difference
and YES it happens on Intel cards (not on Nvidia) (Win 7 OSG 3.4)
Maybe the patched OSG text works better...

I've experienced a similar issue lately where we were running a project on
lower spec systems with only an integrated GPU. On those systems the frame
rate would not show properly, having the same issue as described here, with
some numbers not showing properly.
I did a test on my laptop, and when I force it to use the integrated GPU
(4600) the problems shows up as well. If I switch to use the GTX970M
everything is fine again. This is all on Windows 10, osg 3.4.0
I haven't done any further investigation as the project is not using any
Text objects, but maybe this might help somehow.
Some hardware/drivers don't support texture sub-loading correctly so
the osgText subloading of new glyphs could cause problems, perhaps
this is what you are seeing. It's problem that originally occurred on
Radeon's and some SGI hardware so there is a workaround in osgText
that detects these combinations in drivers, you can also enable the
workaround by setting the env var OSG_TEXT_INCREMENTAL_SUBLOADING to
OFF i.e. under bash you'd do:
export OSG_TEXT_INCREMENTAL_SUBLOADING=OFF
osgtext
Under windows I think it's something like:
set OSG_TEXT_INCREMENTAL_SUBLOADING=OFF
osgtext
The OSG master version has a had a major rewrite of osgText so it no
longer uses the texture subloading as may well just work out of the
box on the Intel GPU/drivers that you have.
