Description
Ubuntu 9.10 Beta (x86-64) with xorg-edgers apt source DG33TL motherboard
Steps to reproduce:
- Install openmsx (0.7.0 will do, early will most likely fail too
- Run and press F10 to open console
- First command: set renderer SDLGL-PP
Now there are various scalers (using GLSL) which can be selected using
set scale_algorithm name
name is one of: RGBtriplet SaI ScaleNx TV hq hqlite simple
RGBtriplet work correctly
SaI Incorrect results
ScaleNx i915_program_error: Unsupported opcode: IF
TV i915_program_error: Exceeded max instructions
hq incorrect results
hqlite incorrect results
simple works correctly (no shader)
The correct results should be visible by selecting non-GL renderer:
set renderer SDL
