   I've seen some issues that appear to be window-manager specific  
(just cosmetic, though - no hangs). Usually, knowing the distro gives  
an idea of which WM is running, but since you're on Gentoo: Which  
window manager are you using?

   There's a GNUstep issue with Compiz WM that can cause similar  
geometry issues - PikoPixel has workaround code for it in  
PPGNUstepGlue_CompizWindowManager.m, so a couple things you might try:


- Force PikoPixel to install its Compiz workarounds: Comment-out line  
84 in PPGNUstepGlue_CompizWindowManager.m, so it always falls through  
to calling ppGSGlue_CompizWindowManager_Install (after the app loads):

+ (void) load
{
//    if (WindowManagerIsCompiz())
    {
         
macroPerformNSObjectSelectorAfterAppLoads 
(ppGSGlue_CompizWindowManager_Install);
    }
}


- Try a different window manager; PikoPixel runs OK on OpenBox  
(Raspbian). There are currently some cosmetic issues on Raspbian with  
fullscreen windows (due to window-bottom decorations), but no hangs  
that I'm aware of.


Thanks,

Josh
