On Archlinux, updating the intel driver from version 2.7.99.901 -> 2.7.99.902 and the xserver from 1.6.1.901 to 1.6.2 (those updates have been packaged that way that they depend on each other) breaks the blender UI (2d parts). This means that when hovering or clicking at any button of the blender GUI, blender won't refresh the screen anymore which means it is impossible to open any menus at all (the GUI is pretty much unusuable). The 3d view works flawlessly and doesn't seem to be affected. Reverting the intel driver and xserver version fixes things, reverting blender from 2.49a to 2.48a not, so it doesn't seem to be directly caused by an update of blender itself. (I hope this bug is in the right category, as blender is an OpenGL app I thought this might be the right place for my first bug report. Otherwise please recategorize accordingly)
glxinfo says the Mesa version is 7.5, but as that doesn't seem available in the version box I left it unspecified there

For reference, software rendering works fine: LIBGL_ALWAYS_SOFTWARE=1 blender
