Picture Window "Jumping" When Making Changes

[frombrandon]

Whenever I make any sort of slider adjustment (or any adjustment at all) the picture shifts (jumps? shakes? flickers?) ever so slightly as it goes pixely until the change has been processed. Any idea why this is happening and how to fix it? I'm enjoying ASP, but when making adjustments — especially a lot at one time — the flickering image drives me nuts.

I'm on a 2.53 GHz Intel Core 2 Duo Mac Mini (OSX Lion)
8GB of RAM
*Plenty* of disk space

Thanks!

frombrandon, I guess what you see are simply intermediate stages of the re-calculation of the image to make it match the adjustments.

But I'm not seeing this in the demonstration videos. I'm not running the bare-minimun system requirements, so I can't understand why it's doing it.

Well, I am on a quadcore with 4GB memory, and I do see it. Maybe the resolution of the demo videos is small enough to make it invisible.

Been seeing it for ages ;-(
a one pixel jump....
Sucks major when trying to judge fine adjustments.

Well, Corel responded to me on Twitter and provided a solution that works for me. I ended up just needing to switch High Quality Previews on. I'm guessing this adds a teeny bit of time to the processing, but having that flickering gone makes all the difference.

That's, File>Preferences>Display toggle with 'Show Only High Quality Previews'

Thanks, Brandon, I will try this!

Unfortunately, that is no help, this one pixel jump also occurs when quality previews only are selected....

I see a difference. It was more than one pixel but now it's as afx says, one pixel jump.

This certainly worked for me

... no pixel jump here either after activating the high-quality previews.

Even with the Preferences set for High Quality, there are times when a change to the rendering features, Noise Reduction, Sharpness, and other controls fails to refresh the main image, until the cursor is returned to or clicked on the main image portion of the screen.

Hi,
thanx that you mention this ... I also observe this behavior sometimes (seems to miss a trigger/event to really put the results into the window ?) ... also with B5.2.2 and B5.2.3 .
And about the "Jumping" .... yes and no ... sometimes I could see it, but most of the time I only get some "coarse" intermediate image before the good one.

Most of the times when I have noticed the hesitation (i.e. image not re-rendered showing the effect of any change to the control panel's tool) it has been a subtle effect. Almost so imperceptible, that, at times, I mistook that the change had already been applied and I just didn't notice it.

If there were a visible "processing" message (or other brief and small transparent overlay on the image) indicating that the processing was still underway -- and it disappeared when the image was fully re-rendered -- this would be unequivocally clear. For systems fast enough, the feature could be turned off in the Preferences, or it would appear and disappear so rapidly as not to matter for users of such high speed systems.
