What the title says.
I can resolve by hitting F11, then F11 again to get out of full screen mode. This happens when launching Opera from a URL link. However, when clicking on another link after Opera is already open, it will just launch a new tab without the top portion of the screen disappearing.
I have also tried resetting Opera to default settings (keeping data intact).
This has not resolved the issue.
Rebooting PC (Win10 V1809) does not resolve issue.
This issue has come up and disappeared periodically over the past several months, leading me to believe it's related to Windows updates, but I have, in the past, reverted to previous versions without the issue being resolved.
Opera is up to date. Version: 60.0.3255.84
Any ideas for troubleshooting and/or resolution would be appreciated.
