I recently switched from Fedora 16 to Scientific Linux 6 which is based on Redhat Enterprise Linux 6. I've been writing apps for work using fltk V2.0 for years and still am, however this problem also exists with V1.3.
The problem is evident in the cube test program on both V1.3 and V2.0. When the program is run I get a couple 'XRequest.137: BadWindow' error messages and the windows don't display correctly. I have an nvidia graphic board and use the kmod-nvidia driver from elrepo.org. With Fedora 16 and previous I got kmod-nvidia drivers from rpmfusion.org but they don't have them for el6. Another twist is that the problem only occurs when I use twinview for 2 monitors. When twinview is off the problem goes away. So far I haven't had problems with any programs that don't use fltk. Gnome apps (Image viewer) and Gimp work fine. So kmod-nvidia + twinview on el6 give the problem. Any suggestions?
