Martin, you're running the 0.92 official release from 11/2010 of NXLIB and Microwindows, and line drawing XOR works, but text drawing not, right? The 0.92 release was cut in November from the June 2010 codebase, just before the major driver changes were made. In 0.92, line draws use linear16_drawpixel, which implements XOR with the APPLYOP macro. Text output uses two different routines, depending on whether the text is anti-aliased (freetype/truetype), or bitmap (PCF/FNT/Core). In both these cases, I think I had included the faster blit routines to be used for outputting text. This is either linear16_drawarea for anti-aliased text, or corefont_drawtext for bitmap drawing. I don't think the latter had XOR support, the former may not either. The 0.92 text output tries to use the porter-duff SRCOVER compositing operation for text output for proper anti-aliased drawing, rather than raster operations. I need more info about your font in order to help. After 0.92 was released, and currently in the git repo are heavily rewritten routines that use a new conversion blit architecture for all image output, including text, GrArea, images etc. XOR is fully supported in the blit routines, but still may be overridden by SRCOVER for text output. I will have to look more into this when I can check the source.
