James,

I have seen your previous message on the geda-user list though I'm
not sure if I can help. There were too many changes since version
1.8.2 (which I suppose worked well for you) which would affect the
code behaviour. One question though: have you built 1.8.2 before
or used your distribution package version?

Other thoughts which may be of some help are below.

I've looked at your previous report and see those errors are from
your underlying OS rendering system, that is the bug may be either
in geda-gaf or in some of your libraries/dependences. Or it may be
some race condition. Did you do 'sudo ldconfig' after
installation? If not, there could be some linking issues.

Don't know here. What does it look like? Though I see some
rendering inconsistences for such a string even on Linux if,
e.g. I move the text down a thin line above remains.

Could you try to disable mit-shm extension as described at [1]?

All the issues you've mentioned are related to rendering and you
are the first who is reporting such a weird behaviour. We're
trying to support as many OS's as we could, and nobody had
reported something like this yet. I ran gschem 1.9.2 on M$windows
and it worked OK. I cannot help with the errors reported there
since AFAIUI they are coming from some underlying library. Quick
searching showed the similar issues/messages appear on iphones (in
other circumstances, of course) which use probably the same
rendering libraries as your MacOS. I have no Mac around ;) so
probably people having one could help more.

  Vladimir
