<nouveau> Дивный глюк иксов

Картинка в иксах обезается слева и снизу ~4-5 мм, и на эти 5 мм вылазит справа. Глючат только иксы (1.8.0) -- во фреймбуффере всё нормально. И это не из-за настроек монитора, точно. На скриншотах глюк не виден. Пересобирал всё несколько раз, пробовал разные версии пакетов -- глюк остаётся %]

Кто-нибудь может подсказать, в чём может быть причина?
