@johnston5129 This usually happens due to a browser scaling or sidebar UI glitch. Try these steps:
- Press Ctrl + 0 to reset browser zoom.
- Open Opera's settings and check the page zoom level.
- Disable any extensions that might affect page scaling.
- Restart Opera.
- If the issue continues, update Opera to the latest version.
If the sidebar is still zoomed in while the main browser window zooms out, it may be an Opera UI bug rather than a normal page zoom issue. Report it in the Opera forum with your Opera version and operating system.
