When switching from one high-res image to another one Ristretto currently briefly displays a blank screen. This is quite distracting which is why the previous image should be displayed as long as possible or the preloading algorithm be improved. This way a seamless transition might be possible. (Only guessing here, of course.) For testing purposes create one simple image (a single color is enough) with a resolution at e. g. 2000×2000 pixels. Copy this image and switch from one to the other and back in Ristretto.
Fixed in svn
(In reply to comment #1) > Fixed in svn At least not for me. I still get a blank screen between two images.
Can you try the following experimental version? http://git.xfce.org/stephan/ristretto/snapshot/ristretto-master.tar.bz2 Preloading is not working yet, but it does something.

Yes, there is no distracting black screen anymore. But now there is a distracting buildup process like from progressive JPEG images. Is this intended or will it be removed in future versions? (BTW: Why the change of hotkeys? I initially found myself stumbled because PgDown and PgUp apparently have no function anymore.)

It takes time to load the image at full-size, usually more time then the user is willing to wait. To compensate, ristretto does 2 things: 1) it renders the thumbnail at full-size to give a low-quality impression of what the image looks like 2) it 'preloads' images so they are rendered in the background before the user has the intention of seeing them. This can be disabled because it obviously has implications on ristretto's memory usage. Currently, in the experimental branch, preloading is broken/not-implemented. > > (BTW: Why the change of hotkeys?

The experimental branch uses gtkuimanager for building the menus and controlling the accelerators (or hotkeys). By using this method, the accelerators can be easily changed. Unfortunately, this has implications on the use of keys used for menu-navigation, like PG_UP/PG_DOWN,ARROWS and ESC. Any use for those keys need to be hard-coded once-again :/
Ok, those hotkeys work again :)

The new implementation of the imageviewer and image-list allows for seamless transition between images (without progressive image-loading). Closing this ticket again.
