Bug 510913

Current behavior:

When pressing the right arrow key to browse images (in single image view mode), sometimes it skips an image. It's most frequent but not limited to big (24MP) images.

Expected behavior:

Ideally, one press of the key should equate to moving exactly one image. The clickable buttons in the toolbar behave like I expect they would, so I'm assuming it's bug with the arrow keys.

More details:

What I suspect it's happening that it's registering repeated key-presses when you hold down the key for some time. For example, when I'm on image 1 and I intentionally hold right arrow key, literally nothing changes on screen (including the image and number at the bottom) until I release the key and now I'm on image 47. It should be required to first release the key before you can go to next image.

It would make sense to allow quick scrubbing trough images by long pressing the right arrow in case the viewer would actually show the image I'm on and short press of the arrow would be guaranteed to move by single image. Image loading is painfully slow at full resolution, so the first condition is not possible, and second condition clearly isn't the case. Note that I'm not pressing the key especially slowly, this issue happens in normal day-to-day use, which makes Gwenview completely unusable. I suggest the simplest fix to move image on "key down" and don't allow to move to next image unless key was released.
