From: Louis-Francis Ratté-Boulianne Date: Fri, 6 Oct 2017 05:26:51 +0000 (-0400) Subject: egl/x11: Re-allocate buffers if format is suboptimal X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3160cb86aa9234ff78e11fe7a00f30bfb5cb8445;p=mesa.git egl/x11: Re-allocate buffers if format is suboptimal If PresentCompleteNotify event says the pixmap was presented with mode PresentCompleteModeSuboptimalCopy, it means the pixmap could possibly have been flipped instead if allocated with a different format/modifier.
