From 131a03631208afb1fce90292eb27115511f58257 Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Wed, 18 Jul 2007 20:17:14 +0200 Subject: fix mesa's handling of fbo's / window fb (again) Make sure the relevant fields in window fbs get updated at appropriate time (those are NOT the same as fbos!!!), and fix up related code accordingly. This is a bit ugly, but there's a reason the issues section in EXT_fbo is a couple hundred pages long... Hopefully correct now. --- src/mesa/main/context.c | 12 +++--------- 1 file changed, 3 insertions(+), 9 deletions(-) (limited to 'src/mesa/main/context.c') diff --git a/src/mesa/main/context.c b/src/mesa/main/context.c index 5239e739568..92d8ceda292 100644 --- a/src/mesa/main/context.c +++ b/src/mesa/main/context.c @@ -1496,14 +1496,8 @@ _mesa_make_current( GLcontext *newCtx, GLframebuffer *drawBuffer, if (!newCtx->DrawBuffer || newCtx->DrawBuffer->Name == 0) { _mesa_reference_framebuffer(&newCtx->DrawBuffer, drawBuffer); /* fix up the fb fields - these will end up wrong otherwise - if the DRIdrawable changes, and someone may rely on them. - */ - /* What a mess!?! */ - /* XXX this is still not quite correct.
