If the max screen resolution is 1600 x 1200, then you need to go into the desktop resolution settings of windows and increase the resolution to the maximum supported.
When using PlayCanvas, ensure that the browser window is maximised. ie it’s covering the entire screen.
If you still don’t see the scene listing, when in Chrome and in the PlayCanvas Editor, hold down Ctrl and press - key until you do. This zooms out the page for that domain.
Things may become harder to read/see because you the page is zoomed out but the Editor only supports a minimum screen resolution of 720p or 768p. AFAIK
Just to follow up, @halvves has done an awesome job updating this dialog to render correctly at different screen resolutions. He’ll deploy the fix on Monday.
As it turns out, there are a few other new features on our dev server and we have a few engineers out on vacation, so we have to wait until next Monday when they’re back before we can safely deploy everything. Sorry, my mistake in prematurely announcing yesterday as the deployment date.
