Visual effect flickering problem

Hi,
I've a stack with a windowshape image.
Every time I apply a visual effect (card transitions, objects transitions), at the end of the visual effect the stack seems to have a little flash from behind.
For example:
Code: Select all
on aboutSplash how
if how is "on" then
lock screen
show group "Startup"
unlock screen with push down
else
lock screen
hide group "Startup"
unlock screen with push up
end if
end aboutSplash
also this simple script gives this flickering effect at the end.
Any suggestion?
Paul

I've found similar problems (probably) in the past, posted in the use-revolution mailing list.
http://lists.runrev.com/pipermail/use-r ... 06511.html
http://lists.runrev.com/pipermail/use-r ... 60299.html
but always unresolved.
Any help?

Visual effects seem to get broken and re-fixed every few releases:

There is a stack attached to that last bug report that shows how buggy they are. It's depressing - used judiciously they provide useful feedback to users (witness the way the iPhone transitions between screens).
Please register with quality.runrev.com. You get votes you can assign to bug issues you want to see fixed, and I have it from Runrev that they really do take bug counts into consideration when prioritizing fixes.
Finally, you might find a workaround in some situations by using this sequence:
show screen with visual effect push down
and just avoid the lock/unlock.

Thank you, Bernard, but the workaround gives me an error:
Message execution error:
Error description: Chunk: error in object expression
and it seems unusable in card transition (I've tried some variation).
Anyway, I will vote for this bug on quality center.

Hi, I'm terribly sorry, I made a typo in my example. It should have been:
show group with visual effect push down
There are various ways to specify transitions with visual effects. For example, with cards once can say:
go card 2 visual effect push down
I just had a look in the Dictionary, and for some strange reason the above modification to the 'go' command is not mentioned.
I hope that might be of some help.

Hi Paul,
I experienced unwanted flickering in a recent application. I had gifs as glow effects that were displayed when the mouse-within condition was true. Adjusting the layers of the image and the gif resolved my problem. I am not sure if this is similar to your issue.

Hi Bernard,
the
go card 2 visual effect push down
seems to work like
go card 2
visual effect push down
but the problem persists, at least on stacks with a windowshape image, also using your tip.
Ed: no, my problem is a simple card transition problem.

Updated news:
the flickering problem seems to appear only if the "shadow" stack property is set to true.
Cheers
