Steps to reproduce


Repro Steps:

  1. Visit
  2. Click the button “Fullscreen bare” on the page.
  3. Press esc to transition back to Windowed mode.
  4. Open the web console and observe the results:

Observed: The web console prints something like in this image:

Note that there are two ‘resize’ events received for a unexplainable 1936x993 and 1920x1016 size, and when transitioning back to windowed mode, the resize event for 300x300 is triggered three times.

The test in the page was conducted on a dualmonitor setup where the main monitor is of size 1920x1080, and a secondary monitor with size 1440x900, although suspecting that this does not matter.

Expected Results:

The log should read

“TO FS: CSS size: 300x300, RTT Size: 300x300” bogus_resize_event.html:78
“RESIZED! New CSS size: 1920x1080, RTT Size: 300x300” bogus_resize_event.html:91
“RESIZED! New CSS size: 300x300, RTT Size: 300x300”

Actual Results:
