AllegroGL Know Bug List ----------------------- * Voodoo 5 only seems to support mipmapping for textures that are 32x32 and under. Voodoo 3 supports larger textures with mipmaps. GLU also resizes down to 32x32. Needs investigation * Catalyst 3.10 drivers aren't able to correctly compile the code in exext.c. This looks like a bug in Cat 3.10; with ATI not following the ARB grammar for VP. Works on NV drivers. * "In extextur, the space character is rendered as a small dot when the background is not transparent". This is a bug in the font generation code. We need to make it more solid. Should we remove the cropping code? Should we draw a rectangle before the text? * AGL cannot deal with extensions which name starts with a number (e.g WGL_3DL_stereo_control). It fails at compile-time trying to construct an invalid struct member variable name like allegro_gl_extensions_WGL.3DL_stereo_control. * Functions that do text drawing, rotating and/or flipping to video bitmaps do not work correctly for dest bitmaps that have textures in segments. Bitmap is made segmented if the texture of the size of the bitmap is not supported by the GFX driver (too large or non-power-of-2). The work-around is obvious. * Functions that do text drawing, stretching, rotating and/or flipping to video bitmaps do not work correctly if EXT_framebuffer_object OpenGL extension is not available. * Functions that do stretching, rotating and/or flipping to video bitmaps do not apply rotation and scale to the memory copy. Thus reading from such bitmaps may return unexpected images. * Before any drawing to the video bitmap occurs, when using FBO feature, at least one call to allegro_gl_set_allegro_mode() must be made. This is needed in order for __allegro_gl_pool_texture texture to be created, which is used for FBO drawing. Here's a list of known bugs, that are either unresolved, lack debug information, or the original discoverer dispeared without confirming whether the bug still exists or not. We would appreciate some feedback on those: * The Allegro mouse cursor doesn't work. This is due to GL not being able to operate accross threads and assynchronously. Potential resolve: make agl_flip() draw the mouse cursor. * On Win32 platforms, the mouse cursor (Windows style) is not always hidden in fullscreen mode. Workaround while the bug is not fixed : call 'set_gfx_mode(GFX_TEXT,0,0,0,0)' before the actual 'set_gfx_mode' (workaround suggested by Martin Dusek).
