Description Ivan Vucica 2007-09-11 09:09:31 UTC 
I am not very proficient in SDL, however I have observed behavior of game Battle for Wesnoth and it appears that, with SDL_VIDEODRIVER=fbcon there's no doublebuffering. Also, there are some mouse cursor quirks. 

Easiest way to see this in action is running wesnoth with the appropriate video driver, and then going to credits. Much visual flickering occurs. 

I have also reported this bug to Wesnoth's bugsystem here:

Comment 1 Sam Lantinga 2007-12-29 12:18:42 UTC 
This is usually caused by an application requesting a hardware video surface and not correctly handling it.  The simple fix would be to remove SDL_HWSURFACE from the video mode arguments.

Please let me know if this isn't the case!
