Describe the bug:
When the servo starts, the content in the window is squeezed.

After resizing the window (even just a little bit), it goes back to normal.

This happens on my sway+nvidia setup, but not on my i3+nvidia setup.

I didn't use any HiDPI setting.

To Reproduce:

1. Build servo: ./mach build -d
2. Launch servo: SURFMAN_FORCE_GLES=1 ./mach run -d
   The variable SURFMAN_FORCE_GLES=1 is used because of this issue Empty window on Wayland with Nvidia GPU #29463 .
