SUMMARY: Sol8 / x86 / S3Trio3d / Xsun loops

I got no replies (and wasn't really surprised - it was a long shot)

I do have a work-a-round that may be of interest as it's a general one that
can help with many obscure display driver problems.

Get and install a copy of VNC from http://www.realvnc.com/ and configure the
vncserver start up script to run the problematic application.  Whatever blt
coperation was causing the problem within the application is not used by
vncviewer and so the display works as expected.

Amazingly even on a 400MHz PC using Netscape via VNC is actually not too
horrible even on graphics intense web sites.

Of course, if this wasn't a work PC I'd solve the problem by getting a real
display card and replacing the noname rubbish I have to use :-)


Question was...

> I'm running x86 Sol8 + latest recommended patches with a noname S3 Trio3d
> video card and the standard Sun provided Xsun. Under some conditions Xsun
> will go into a loop and has to be killed and restarted.
> 
> The conditions are quite specific -- When using Netscape Navigator 4.7* and
> clicking on a mailto: URL will trigger the problem; using Netscape 7
> clicking on the Edit->Preferences will also trigger the problem.
> 
> In both cases a partially completed window is displayed and then Xsun loops.
> 
> I've managed to capture some stack info from a run with Netscape 7...
