@crossLain It seems like the issue you're facing with WhatsApp Web on the web panel could be related to how resources are being allocated or rendered differently in a web panel compared to a normal browser tab. Here are some steps that might help resolve or mitigate the issue:
Check for hardware acceleration settings: Ensure hardware acceleration is enabled or disabled (toggle this option) in your browser settings to see if it makes a difference.
Resource usage monitoring: While using the web panel, open the browser's task manager (e.g., in Vivaldi, Shift + Esc) to monitor resource consumption. If WhatsApp Web is consuming excessive resources, it might point to a rendering issue specific to the panel.
Switch to a standalone desktop client: If the performance issues persist, consider using the official WhatsAppna Desktop app for smoother performance. It’s optimized for desktop environments and avoids browser-specific quirks.
Browser or profile-specific corruption: Try creating a new browser profile or reinstalling Vivaldi. Sometimes profile corruption can cause unexpected slowdowns in specific contexts.
Let me know if any of these suggestions improve your experience with WhatsApp Web!
