Ok I had the same exact problem as most. I can start windows and get some odd graphics issues on the right and bottom side of the screen and they won't go away. I could check or uncheck the start in windowed mode and it would do nothing for me so I came across a temp fix until someone can dig a little deeper for the answer.
1. Launch "Launcher_gui" first.... don't just use "Launch" from the windower 3.3 folder.
2. Make sure you check "Hide Borders" in the launch tool. I also made sure all resolution settings were the same in all files just in case.
3. The game should launch up just fine with no graphics overlay issue... but you still can not maximize or minimize. This is easily solved if you go into the console for windower and type "window_toggleframe". I actually have to type that command twice and it will bring my frames back up. And from that point on you can maximize or minimize. This has to be done everytime you launch the game for now until they fix the issue but it fixed mine and it was the only fix available that I could find. I couldn't find any issue with resolution settings anywhere but I am sure I am overlooking something.
Anyways I hope this helps. smile.gif Good luck. Worked for me atleast lol.
