Teeworlds up to 0.4.3 has worked fine, if sluggish.  Starting 0.5, the screen goes black and hangs.  Running teeworlds from the terminal, there appears to be an X error.  Can anyone confirm the cause of this error?  Is it due to a new requirement for 24bit color support, perhaps?  Any workaround?

Extract from the terminal output:

...
