Just a follow up to my earlier message. I don't know if anyone at RSI
is interested in such things, but here it is just in case. I have
several workarounds and I don't use IDLgrWindow that often, so it's
really no big deal for me.
I don't know when the problem started because I don't use IDLgrWindow
that often. Most of my IDL code processes things off-line so there's no
need to display an image to the user. Anyway, the only time the "white
out" occurs is if I use hardware rendering in an IDLgrWindow. Software
rendering is fine. I have had no problems using an IDLgrBuffer and then
either displaying the image in direct graphics or saving it to a file.
I'm using Fedora Core 4 and have an "old" ATI Radeon Mobility 7500
graphics card. This card is one which ATI no longer supports and the
only Linux drivers available come via the DRI project. I'm currently
running Fedora Core 4 with X.org 6.8.2 and using IDL 6.2. I don't know
if there was an update to X.org or to the DRI driver that would have
caused this, but that's the only thing I can figure. ATI stopped
supporting the Radeon 7500 a while back, so I know that I must have been
using the DRI driver for some time, but this is the first time I can
remember seeing such a problem.
Anyway, there's the scoop for what it's worth. Now, I'll go back to
making my pretty plots. :-)
