You may want to upgrade to the proprietary drivers; the noveau driver isn't as well supported.
Hello @lumag, are you still experiencing this issue with an up to date system? If you are, this should be brought to the attention of the game's devs.
Closing as general video driver quality from 2013 is no longer relevant.
Nothing extracted yet.
After one of recent updates, Waveform starts with fullscreen resolution (but not in fulscreen mode). Previously Waveform displayed additional window with mode selection. Now I see that window being opened and immediately disappearing, so no mode selection is possible.
System details: Debian 7.0 weezy (testing), nouveau video driver.
