From cbfe29cdee5d338a25f13abbbb191b80428d05c8 Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Mon, 16 Jul 2007 18:21:36 +0200 Subject: [PATCH] fix bogus fb/drawable information the framebuffer objects attached to drawables can have invalidate state associated with them, since for the window framebuffer this is per-context state and not per-fbo state. Since drivers rely on that information (otherwise would need to check if currently the window-framebuffer is bound in a lot of places) fix it up in _mesa_make_current (ugly). (Brought over from i915tex_privbuffers, where it fixes xdemos/wincopy when switching to front buffer rendering.) --- src/mesa/main/context.c | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/src/mesa/main/context.c b/src/mesa/main/context.c index 21adcf32106..2ad1badac70 100644 --- a/src/mesa/main/context.c +++ b/src/mesa/main/context.c @@ -1495,9 +1495,20 @@ _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!?! */ + int i; + GLenum buffers[MAX_DRAW_BUFFERS]; + for(i = 0; i < newCtx->Const.MaxDrawBuffers; i++) { + buffers[i] = newCtx->Color.DrawBuffer[i]; + } + _mesa_drawbuffers(newCtx, newCtx->Const.MaxDrawBuffers, buffers, NULL); } if (!newCtx->ReadBuffer || newCtx->ReadBuffer->Name == 0) { _mesa_reference_framebuffer(&newCtx->ReadBuffer, readBuffer); + _mesa_ReadBuffer(newCtx->Pixel.ReadBuffer); } newCtx->NewState |= _NEW_BUFFERS; -- 2.30.2
