On current bzr trunk, I noticed that Widelands is extremely slow (less than 1 fps) in-game in OpenGL mode.

Workaround: From the main menu, go to Settings -> Advanced Settings and turn off OpenGL. If even the main menu is too slow, you can start Widelands with the parameter --opengl=0 to force turning off OpenGL.

This happens with the following system setup:
- Lenovo Thinkpad T60 with Intel 945GM family integrated graphics
- Ubuntu 12.04 (Precise Pangolin)
- Linux kernel 3.2.0
- X.Org Intel driver 2.17
- Mesa 9.0

I know this system to be able to run Widelands in OpenGL in principle, though too many components (both Widelands and the Linux installation/graphics driver) have changed to be able to isolate the culprit quickly.

If anybody else sees very slow OpenGL performance, it may be a good idea to collect system specs in this bug report. I'll keep investigating this myself as I find the time to do so.
