Hash : 29639857
Message : D3D11: Work around Intel uniform buffers bug. When copying from a staging buffer to a uniform buffer, the first upload would be incorrect. Work around this by trying to upload directly to a uniform buffer on the first BufferSubData call. BUG=chromium:593024 Change-Id: I0df3a1422b962bf3ece5d445f435df01e3544b67 Reviewed-on: https://chromium-review.googlesource.com/368774 Reviewed-by: Geoff Lang <geofflang@chromium.org> Reviewed-by: Corentin Wallez <cwallez@chromium.org> Commit-Queue: Jamie Madill <jmadill@chromium.org>
