I am attempting to figure out if a problem with fonts in Wine is related to my OpenGL driver (r600g). How can I temporarily switch to the llvmpipe software renderer to perform testing, then switch back to r600g? I am using Kubuntu 16.04 with Radeon HD 3200 graphics. Thanks.

You can use the LIBGL_ALWAYS_SOFTWARE environment variable to force software rendering on a per-application basis:LIBGL_ALWAYS_SOFTWARE=1 [application] [arguments ...]It only works if you are using mesa (which you probably are).
