+1. Here is bug-report. Feel free to mark that this bug also affects you.
Option 1) Use Chromium instead. I've seen your same issue within google-chrome-stable but everything is clean within Chromium.
Option 2) If you installed NVIDIA 390.48 directly, uninstall it and then re-enabling the driver using the Additional Drivers tab within Software & Updates.
