Description Cyril Brulebois 2010-08-06 19:02:33 UTC
Chip: 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
Kernel: 2.6.32 as patched by Debian (many DRM fixes from 2.6.33.y, etc.)
Server: 1.7.7 as patched by Debian

With either 2.12.0+legacy branch or master (as of 6304cb0) I'm hitting the following assert:
                                assert (uxa_pixmap_is_offscreen(src_pixmap));

To reproduce, just start the 'sm' program (http://www.joachim-breitner.de/projects#screen-message) with a random string, and exit it (hitting 'q').

    uxa: Fallback if faced with large A1 glyphs.
    Rather than assert, we should fixup the use of large A1 glyphs. However,
    the simplest approach is to simply fallback to s/w.
