The assert is bogus since there's no problem with texture width/height being 2048 (the width/height programmed is width/height minus one). OTOH though the programmed size for scissor rect should be width/height minus one too otherwise bad things may happen (as it is inclusive, and there's not enough bits for more than a value of 2047). --- diff --git a/src/mesa/drivers/dri/r200/r200_blit.c b/src/mesa/drivers/dri/r200/r200_blit.c index fbded5314e5..e3124b312f4 100644 --- a/src/mesa/drivers/dri/r200/r200_blit.c +++ b/src/mesa/drivers/dri/r200/r200_blit.c @@ -108,8 +108,8 @@ static void inline emit_tx_setup(struct r200_context *r200, uint32_t txformat = R200_TXFORMAT_NON_POWER2; BATCH_LOCALS(&r200->radeon); - assert(width <= 2047); - assert(height <= 2047); + assert(width <= 2048); + assert(height <= 2048); assert(offset % 32 == 0); /* XXX others?
