Reporter: Avidan Chen

After upgrading from Phonegap 1.2.0, there's a noticeable white flash (maybe half a second) before displaying the first html page.

[jira] [Updated] (CB-554) White flash before showing the html page

Posted by "Joe Bowser (JIRA)" <ji...@apache.org>.

Joe Bowser updated CB-554:
--------------------------
Priority: Trivial (was: Minor)
This issue isn't noticible when we test it on the Samsung Galaxy Nexus with 4.0.2 (for some reason I don't have 4.0.4 pushed to it yet), on the Nexus S with 2.3.6 or with the Samsung Galaxy S2 with 2.3.4 (for some reason international versions are behind). I'm going to move this bug to trivial, since it's always existed and this bug seems to be about perception more than anything else.

[jira] [Commented] (CB-554) White flash before showing the html

Joe Bowser commented on CB-554:
-------------------------------
That "white flash" has always been there, if it appears longer now, it's because there's an issue with the execution of your Javascript. Can you post a sample of this bug so that we can figure out where things are slowing down for you?
Also, you may be able to mitigate this with a splashscreen.

I notice this as well, fwiw.
The white is, I believe, the body background color initially before anything happens.

Avidan Chen commented on CB-554:
--------------------------------
Well, it wasn't there when I was running 1.2.0. And nothing in my code changed. I simply upgraded to 1.6.1. I also upgraded jQuery mobile to 1.1.0, but I did that prior to upgrading phonegap and I thoroughly tested it without any issues. Only after updating phonegap it started happening.
By the way, I didn't use a splashscreen in 1.2.0. nor do I use it now because I need the ability to hide it after I'm done caching pages (as far as I could tell, hiding the splash screen on demand in javascript only works in iOS). Instead, the background image of my first html page serves as the splash screen, and when I'm done caching I just switch to the next page.
Now, I did try to use a splashscreen in 1.6.1 just to see if it helps, but there was no change.
After further investigating this issue, I noticed it happens even before deviceready fires. What's wierd about it is that it doesn't happen all the time. Most of the times I start the app, but not every time.

Joe Bowser commented on CB-554:
-------------------------------
@Lindsey This is the colour of the WebView before anything loads, not the background which defaults to black. This is most likely caused by a JS issue, which is why I would like an example so that we can look into this further. Without code, we can just say that the JS execution is slow.
Do you have an example that we can look at?

Joe Bowser resolved CB-554.
---------------------------
Resolution: Won't Fix
We already have work-arounds for this issue, including splashscreens. If people are seeing a white flash, their Javascript performance may need to be looked at as well.
