Anyone else using 2 4K displays getting the contents of the window jumbled to unreadable muck if they resize a window more than 2000ish wide? I'm primarily seeing it under KDE but XFCE will do it too. Only happens about 20% of the time... Except: Gwenview always. and Dolphin 60% of the time. Seems to only happen with 2 4k monitors with a single X session spanning both windows. Problem is in all current Release version of FreeBSD and I'm using the Nvidia driver for my GTX970. Just curious wondering if anyone has seen it and if there is something I can pass in xconf that might fix it. I's most likely a problem with the Nvidia code but I don't think I'll have a lot of luck getting them to fix it... Wish they we not so anal about their driver code. Its pretty easy to work around just don't get greedy with how large you make you windows. But once it mucks up the only way to really fix it is restart X since the affected app will come back up messed up even if you kill it and start a new window. -- esp
