The other work around I found was to click an effect in CompizConfig Setting Manager --> Effects. Some command is run at the backend which fixes the bad borders.
I also notice another issue with the new driver. The minimise button of the widow can fail to work. Also, sometimes the mouse click becomes unresponsive. I have to click the maximise button twice (i.e. the window will maximise and then revert to its normal size before it can work again) to resolve these issues. Hope these findings can give insights to fix these bugs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1667158 Title: Borders of pop-up windows are displayed badly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-375/+bug/1667158/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
