I have the exact same issue, but I haven't installed the beta yet, I'm using the stable 11.0 release. Also probably not related, but I'm using the LBPlex condensed theme.
It happens when: 1. right clicking a game; 2. when after clicking edit and view the images - pressing the >
But it is random and I can't reproduce everytime I want. Didn't count, but the chance of happening is about 5% of the time on my end. I'm adding some translated games so I'm right clicking and edit a lot.
Probably not the right place, but I have some suggestions:
. It would be nice to limit the amount of images downloaded of a category, like I got 10 ingame screenshots but I just wanted 1 and have to remove those by hand;
. An easy way as an option to choose what it comes first on the game details column. Like the screenshot before the notes, etc.
. Typing on launchbox to be similar to windows, like if type ch fast, it should be a game starting with ch, but on launchbox it goes to the last typed letter.
. Some more love to the wall view on big box, it would be awesome to have a wall view that has the same features and look close to launchbox. I tried to edit some themes to add a wall view but got discouraged that is lacking a lot of options (the zoom out when selecting a game is 3D and not at the axis of the game; selecting a game is always centered so the wall view begins scrolled down, couldn't find a way to add the names of the games in front of the boxart like in the lauchbox, sort by favorites or star rating, etc.)
