Critical issue: On macOS 27, when the MacBook screen is locked or the device enters sleep mode, the application becomes unresponsive after the MacBook is unlocked or wakes up.
After reopening the MacBook, the application may still display the current webpage normally, but any area outside the visible webpage content cannot be clicked or interacted with. The app becomes laggy and almost unusable until it is restarted.
for details, I will record the video

Vivaldi toolbar stops responding after wake
Environment: macOS 27.0 (26A428), Vivaldi 8.2.4133.80, Stage Manager enabled, MacBook display plus one external display.
Issue: After sleep/wake, the web page remains clickable, but Vivaldi's toolbar, tabs, extensions, and browser buttons stop responding.
Evidence: WindowServer logged 34,574 occurrences of:
_CGXPackagesSetWindowConstraints: Invalid window
During the failure, Vivaldi's visible window was incorrectly registered as only 145×149 px at (15,515), approximately the size of a Stage Manager thumbnail. Vivaldi, GPU, and extension processes were not frozen.
Verification: The issue does not occur when Stage Manager is disabled.
Conclusion: This is most likely a macOS Stage Manager/dual-display window-geometry bug after wake. Restarting Vivaldi temporarily fixes it; disabling Stage Manager prevents the issue.
