[Octave-bug-tracker] [bug #54396] Removing Opengl32.dll speeds up plot navigation, but it prevents saving plots using saveas or print

[Markus Mützel]

Follow-up Comment #4, bug #54396 (project octave):

I think we are building opengl32.dll with "mesa.mk" in MXE Octave. It contains
the following configure options:

    $(PKG)_CONFIGURE_OPENGL_OPTIONS := \
      --enable-opengl --enable-egl --enable-gles1 --enable-gles2 \
      --with-gallium-drivers="swrast" --with-dri-drivers="" \
      --with-platforms="x11"


Does that mean we are building the older swrast driver?

The mesa docs [1] say to use the following switches to build the Gallium
llvmpipe driver (for a Linux target):

  ./configure --enable-glx=gallium-xlib --with-gallium-drivers=swrast
--disable-dri --disable-gbm --disable-egl
  make


To be honest, I don't know all the intricacies to make any further comments.
