--- Comment #7 from Kristian Høgsberg <[email protected]> --- I'll post this to mesa-dev for review, fixes the problem here: commit fad655f0ce208ae985c62c936d26e20d8a22f897 Author: Kristian Høgsberg <[email protected]> Date: Fri Jan 17 16:55:31 2014 -0800 i965: Only update renderbuffers on initial intelMakeCurrent We call intel_prepare_render() in intelMakeCurrent() to make sure we have renderbuffers before calling _mesa_make_current(). The only reason we do this is so that we can have valid defaults for width and height. If we already have buffers for the drawable we're making current, we don't need to do this. https://bugs.freedesktop.org/show_bug.cgi?id=72540 https://bugs.freedesktop.org/show_bug.cgi?id=72612 Signed-off-by: Kristian Høgsberg <[email protected]> diff --git a/src/mesa/drivers/dri/i965/brw_context.c b/src/mesa/drivers/dri/i965/brw_context.c index 78c06fc..b23cdef 100644 --- a/src/mesa/drivers/dri/i965/brw_context.c +++ b/src/mesa/drivers/dri/i965/brw_context.c @@ -911,6 +911,7 @@ intelMakeCurrent(__DRIcontext * driContextPriv, if (driContextPriv) { struct gl_context *ctx = &brw->ctx; struct gl_framebuffer *fb, *readFb; + struct intel_renderbuffer *rb = NULL; if (driDrawPriv == NULL && driReadPriv == NULL) { fb = _mesa_get_incomplete_framebuffer(); @@ -918,6 +919,7 @@ intelMakeCurrent(__DRIcontext * driContextPriv, } else { fb = driDrawPriv->driverPrivate; readFb = driReadPriv->driverPrivate; + rb = intel_get_renderbuffer(fb, BUFFER_BACK_LEFT); driContextPriv->dri2.draw_stamp = driDrawPriv->dri2.stamp - 1; driContextPriv->dri2.read_stamp = driReadPriv->dri2.stamp - 1; } @@ -929,7 +931,12 @@ intelMakeCurrent(__DRIcontext * driContextPriv, intel_gles3_srgb_workaround(brw, fb); intel_gles3_srgb_workaround(brw, readFb); - intel_prepare_render(brw); + if (rb && !rb->mt) { + /* If we don't have buffers for the drawable yet, force a call to + * getbuffers here so we can have a default drawable size. */ + intel_prepare_render(brw); + } + _mesa_make_current(ctx, fb, readFb); } else { _mesa_make_current(NULL, NULL, NULL); -- You are receiving this mail because: You are the assignee for the bug.
