Same, I think i've worked out whats happening, in this case my sg1000 has a mix of images such as these, when LB chooses the smaller image it doesnt blur, my creativision are all the smaller images and none of them blur.
I don't know if this is a bug but a similar thing happened to me, i created a playlist inside a platform category and named it 'All', it just replicated the main All list and delete and edit were greyed out. I used the Tools>Restore Data Back-up to revert to before i'd made the change to get rid of it.
I worked out how to do it! You just copy the xaml file and rename it to whatever your playlist is named, or i guess you could also just rename the original xaml if you only wanted those views for playlists.
I was converting things to CHD a few weeks ago and ran into the same issue with Sega CD, i just tried without RL (as i hadnt before) and yes it works.
Both PS1 and Saturn CHDs work ok through RL.
Yeah, i just renewed my licence and updated. My point is if you want themes in BB you have to have then in LB too, which wasnt the case before? (unless im mis-remembering). Either way BB needs its own video priorities.
