Just reinstalled my OS and Lutris 5.13 but found Lutris no longer displayed my custom banners. I install the banner by:
1/ right click the game in the main window and select configure
2/ this takes me to the game info screen with 3 boxes at the top to include custom artwork, custom cover art, banner and icon
3/ I click on the banner box which opens a window, please choose a custom image and I choose the image I was using prior to my OS upgrade. Alternatively I choose an image from ~.cache/lutris/banners. The banner is not displayed in either case.
It seems I might be missing a library or perhaps something else, anyone have any ideas?
