What's the problem? Describe what went wrong.

When the debugger panel (and presumably any other panel) is opened, the render surface is only partially visible.

What steps will reproduce the problem?

1. Launch Dolphin with the -d flag.
2. Launch a game.
3. Observe that only a small part of the screen is visible.

No

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

    Renderer: Handle resize events on-demand instead of polling
    
    We now differentiate between a resize event and surface change/destroyed
    event, reducing the overhead for resizes in the Vulkan backend. It is
    also now now safe to change the surface multiple times if the video thread
    is lagging behind.
