From dd072cf4b131c8aa9e8be0ff24b70856fe39285e Mon Sep 17 00:00:00 2001 From: Daniel Stone Date: Fri, 21 Jul 2017 12:05:17 +0100 Subject: egl/wayland: Ignore invalid modifiers If the underlying driver does not support modifiers, dmabuf will still advertise formats through the 'modifier' event, but send them with an invalid modifier. Ignore them if this is the case, rather than passing them through to the driver.
