Dunelegacy on Raspberry pi

[symbios24]

Hello there i have a Raspberry pi3 and tried dune legacy for arm version 0.96.4 upon starting a new campaign the game was flickering i searched online for a solution and i found that disabling double buffering solves this problem,but double buffering is available on version 0.96.3 and earlier not in newest version,is there a way to disable it on newest version?

Thank you
