Xorg crash - GLSL compile failure

[Unixnut]

Hi all,

I've got an new install of FreeBSD (that I just upgraded to the latest 14.1-RELEASE-p5) and all configuration went well until it came to configuring my desktop environment. I can start an X session fine (using startx) and fluxbox loads ok. However when I try to open a rxvt terminal X (version 1.21.1.13) promptly crashes.

This happens every time so I was able to capture a log:

I notice the error "Failed to compile FS: 0:1(10): error: GLSL 1.30 is not supported. Supported versions are: 1.10, 1.20, and 1.00 ES" and was wondering if something went wrong during the package updates and some packages didn't get properly updated?

Anyone seen this before and can recommend a fix? I found this forum post and I can confirm the workaround of adding Option "AccelMethod" "none" has allowed me to use my desktop and terminals, but the expense of no acceleration.
