Performance is terribly sluggish with visible loading lag, upscaling of smaller images (ie Fit view) lags & produces jagged artifacts in all images, gif viewing takes ages … it is almost unusable for me.
Downgraded to 21.04.3 and the difference is light and day. Fast, snappy and no jagged artifacts.
This is the problem with community projects like KDE … change happens for the sake of change and not because it is needed or warranted.
I don’t keep gwenview open and browse, I open image files singularly from a file manager to view.
Is gwenview now buffering / pre-loading images in a directory when the app opens? Is that how they have “improved” performance? I don’t think they are doing it as an asynch background task either.
Just opened an image in a directory with about a thousand images / memes / photos / wallpapers (ie sorting folder) and it took well over 5 seconds to load. The image was greyed out, no loading cursor or animation, and the app was unresponsive the entire time.
Progressed through each image relatively quickly, albeit with scaled image quality, but the first one was a doozy.
Even in directories with fewer images the app does not load a single image instantly like the previous versions. There is a noticable lag.
Try scaling smaller images, it is horrendous, with no anti-alias option in the settings.
Gwenview needs to be more like Cher … she never changes.
