For anyone still running in to this, the main reason I wanted the title bar was to be able to see the Ubuntu / Linux system context menu, to set "Always on Top". There doesn't appear to be a way to make the system title bar show up, but you can get that context menu by hitting Alt+Spacebar.
@Happy-Axolotl said in Pages lag in Opera GX:
The computer is powerful, nothing is overloaded, there are no limits, the Internet is in order, but scrolling on any pages is still jerky, and when new information starts to download from the site (for example, vk.com), the entire browser starts to slow down.
There are no extensions that can make websites slow down so much, VPN is not included, and the browser itself was installed only yesterday. In other browsers (for example Firefox), everything is completely fine, everything is smooth and without freezes. What is the problem?
My browser behaves badly. One open tab sometimes takes up 7 GB of memory. The browser slows down, the video goes to the full-screen window for 2-4 seconds. In games with an open browser, there is freezing and FPS sags. This was not the case with Mozilla's browser.
