Does PtTrend work in PtOsContainer?

(QNX 6.21 PE)

If we put a PtTrend inside an PtOsContainer, it doesn’t draw
at all. Outside the PtOsContainer, it does draw OK.
On the other hand, PtMeter widgets work either way,
although they flicker outside an OsContainer. Is
this what’s supposed to happen?

What’s the best way to use PtOSContainer? One for each
widget that needs it, one for each nearby group of
widgets, or one for the whole window?

We’re running the display in VESA mode, so the PtTrend
draws in “dumb mode” (no grid, etc.)

I have problems with the PtOSContainer too, and after talking to a chap
at QSS, it would appear it has some bugs. I run in VESA too, but I’m
getting an accelerated card soon so I’ll be able to ascertain whether
it’s down to the VESA driver or not.

If you resize the window to force the PtOSContainer to redraw, can you
get it to display?
