[Mesa-dev] OSMesa Virtual Window with height > 16384px

[Phaedra Narayna]

Hi,

I have a OSMesa bug when trying to create a virtual window that is more
than  16384 pixel in height , see below :

*Command:*
#headless_shell --screenshot --window-size="1920x16385" --hide-scrollbars
--no-sandbox http://linuxfr.org
*Error Msg:*
[0920/154515:ERROR:gl_context_osmesa.cc(72)] OSMesaMakeCurrent failed.
[0920/154515:ERROR:gles2_cmd_decoder.cc(4992)] GLES2DecoderImpl: Context
lost because context no longer current after resize callback.
[0920/154515:ERROR:gles2_cmd_decoder.cc(5108)] Error: 5 for Command
kResizeCHROMIUM
[0920/154515:ERROR:gl_context_osmesa.cc(72)] OSMesaMakeCurrent failed.

I am using OSMesa on Archlinux :
https://www.archlinux.org/packages/extra/i686/mesa/ , mesa 12.0.3-1 as this
time of writing.

I have checked with the HeadLess Chromium project as per this thread:
https://groups.google.com/a/chromium.org/forum/#!topic/headless-dev/t0ixeHXCzK0

I have checked with the Skia project as per this thread :
https://bugs.chromium.org/p/skia/issues/detail?id=580&can=2&start=0&num=100&q=label%3AHotlist-Fixit&colspec=ID%20Type%20Status%20Priority%20M%20Area%20Owner%20Summary&groupby=&sort=


Any idea on how to solve this problem?

Thanks,
