@isaacbravosix It's probably a battery saver. Plug in your laptop or disable the feature.

You can also add it as a custom site panel to your sidebar.

1. Enable the flag chrome://flags/#sidebar-site-panel and restart
2. Open sidebar setup and add https://claude.ai/

@Electricjohnny Hi. The bug is fixed in version 128.0.5807.97

Hello!
The issue on Opera/Opera GX has been resolved by Pinterest. Please reload the page. If problems persist, clear your site data (cache and cookies).

@Kasumikoo are you using any other anti-virus or firewall software? If so try temporarily disabling them.

Sometimes renaming opera.exe helps. Here's instruction how to do it: https://forums.opera.com/topic/85376/known-issue-opera-gx-not-opening

Hello,
Our investigation found that PC Matic SuperShield was blocking the new Opera GX. The PC Matic team has added Opera browsers to the allowlist, and restarting your PC should resolve the issue.

The issue is fixed in Chromium 140.0.7339.249. Please update your Opera GX to 124.0.5705.38 version.

Dear Users,
if you've recently started seeing a black, white, gray, or completely empty screen when launching Opera GX, you are likely encountering a known bug related to experimental Chromium flags.
This issue is often caused by a bug when the experimental Chromium flag #use-angle is manually set to non-default options like OpenGL or D3D9. The screen will appear broken and unusable, preventing you from accessing the browser settings.

Here is a step-by-step guide to temporarily launch your browser and permanently apply the fix.

Step 1: Launch Opera GX without experiments (flags)

Method A: Modify the Shortcut
This is the easiest method for most users.

• Right-click on your Opera GX shortcut (on your desktop or Start Menu).
• Select Properties.
• In the Target field, add the switch -no-experiments to the very end. Make sure there is a space between the existing path (the closing quote " if it's there) and the switch.
  Example: "C:\Users...\opera.exe" -no-experiments
  
• Click Apply and then OK.
• Double-click the modified shortcut to launch Opera GX. It should now open normally.

Method B: Use the Command Line (Advanced)
If you prefer not to modify your shortcut, you can use the Command Prompt or PowerShell.

• Open Command Prompt (CMD) or PowerShell.
• Navigate to your Opera GX installation directory.
• Run the browser with the switch:
  .\opera.exe -no-experiments

Step 2: Change the ANGLE Flag

Once you have successfully launched Opera GX using one of the methods above, you can now change the problematic flag back to a stable setting.
In the Opera GX address bar, type or paste the following address and hit Enter: opera://flags/#use-angle (or chrome://flags/#use-angle)
This will jump you directly to the setting "Choose ANGLE graphics backend."
Change the dropdown menu for this setting from the problematic value (likely OpenGL or D3D9) to either Default (Recommended) or D3D11 (If Default does not resolve the issue)

A Relaunch button will appear at the bottom right. Click it to restart your browser.

Your Opera GX should now open correctly without needing the -no-experiments switch!
If you used Method A in Step 1, you must now go back to the shortcut properties and remove the -no-experiments switch you added. It is no longer needed.

@LordMaverick05 Thanks for the info. This is not Opera's issue if the same version works on your desktop PC. What OS are you using on your laptop?
Please try downloading Opera GX from Microsoft store.
