AWT painting problem on Linux

Classic Servoy
1

When I load our application on Linux (Fedora Core 3) the screen doesn’t paint properly. Only portions of the window show up. No one else running the application on Window or Mac has this problem. The error is always a div-by-zero in the AWT event queue. Anyone seen this before?

Thanks,
Jason

which JVM ?

I’ve tried with 1.5.0-03, -06, -08 and 1.6 beta 2. Have also since posting installed Ubuntu 6.06 but no luck.

That’s interesting to see, although the related bug on that page indicates that both have been fixed (closed on 7/18/06). Still, makes me wonder if mucking with my fonts might help.

Thanks,
Jason

reading between the lines…the specified font cannot be found and so a font size of 0 is being specified…so, playing with your fonts will probably resolve the problem :)

Wish it turned out to be that simple. Have tried now a number of fonts, not only present on my system but the currently selected font in my desktop environment (app, document, desktop, window, and monospace).
