Hi, it is unlikely to find help with such an old Weston, even more so with the fbdev backend which at least I would like to just delete already. But the fbdev backend is still in Weston, so I'd recommend trying a more recent version. You can also check git to see if there are code changes in the fbdev-backend. I don't think FBIOPUT_VSCREENINFO at every repaint is good in any case. You might be interested in reviewing this patch or the whole series: https://patchwork.freedesktop.org/patch/200333/ What I've occasionally tested the fbdev-backend, I've never needed a call to FBIOPUT_VSCREENINFO, so your use case must be somehow different. Explaining exactly how and in what kind of a system and environment you are running Weston could help. E.g. is it a secondary fbdev device, or using UDL driver. Thanks, pq
