[IE11] Splash appears in the top left of the screen at startup, then centers

[phet-steele]

From @BryceAG in phetsims/tasks#764 (comment)

On Win 7, IE the splash will pop up in the top left corner for a brief moment, then center itself. Happens regardless of window size.

Verified on Win 7 and 8.1, IE11 with this link http://www.colorado.edu/physics/phet/dev/html/energy-skate-park-basics/1.3.1-dev.3/energy-skate-park-basics_en.html

Could it be related to the CSS in #407 ?

[samreid]

#407 was attributed to a minor image dimension change. We can see if an image size problem is causing this issue as well (say, if the image has size 0,0) at the beginning.

I can still see the problem in my virtual box IE11 for http://www.colorado.edu/physics/phet/dev/html/energy-skate-park-basics/1.3.1-dev.3/energy-skate-park-basics_en.html

However, when testing with a built faradays law using the fix from #407 I no longer see the problem.

Dev version is here: http://www.colorado.edu/physics/phet/dev/html/energy-skate-park-basics/1.3.1-dev.5/energy-skate-park-basics_en.html

Well it is still a problem in that version, not sure why.

[samreid]

@jonathanolson and I considered the following strategies:

1. Let it be buggy on IE11 (the splash screen starts in the top left then jumps to the middle)
2. Don't show any loading/splash screen on IE11
3. Show the loading bar but no image on IE11
4. Rasterize the splash images instead of using SVG
5. Hard code the image sizes in code (may get out of sync and be harder for 3rd parties to add their own logo)

[samreid]

I went with (2) for now since it was extremely simple to implement. @ariel-phet can you please recommend a way to proceed here? We are not sure how much time to spend getting the splash screen to look good on IE.

[ariel-phet]

@samreid I think i would rather leave it buggy then have no splash/loading screen. A blank screen might make the user think the sim is not loading on a slower internet connection with IE.

[samreid]

This is out for testing in the aforementioned issue.

[phet-steele]

Doesn't really look like there is anything here to test? There was a commit that changed some things, then a second commit that just reverted it. Yes...it is still buggy on IE11 but that's what we expected. @samreid should we mark this deferred (or wontfix) and leave open for later?

[samreid]

I guess close as wontfix?
