--- Comment #2 from Julien Nabet <serval2412 at yahoo.fr> ---
Unwinding a bit, we got an assert because:
we don't enter if bTryDirectPaint block (see
https://opengrok.libreoffice.org/xref/core/vcl/source/outdev/bitmap.cxx#661)

659 bool bTryDirectPaint(!pDisableNative && !bHMirr && !bVMirr);

and gdb indicates bHMirr = true (whereas the others are false)

bHMirr = true because
637  const bool bHMirr = aOutSz.Width() < 0; (width = -1)

some frame above in the stack, we find:
    285                     rTargetSurface.DrawBitmapEx( aOutPos, aOutputSize,
    286                                                  BitmapEx(
maContent->GetBitmap(),
    287                                                            aAlpha ) );
see
https://opengrok.libreoffice.org/xref/core/canvas/source/vcl/spritehelper.cxx#285

To be continued because I should add some traces to be sure.
