--- Comment #3 from Steffie <steffie5...@zoho.com> --- (In reply to Ivan Čukić from comment #2) > p.s. If you create a new user, does it show black thumbs for it as well? Yes, just the std wallpapers already available in Maui by default, + some others downloaded via the std kde tool "Get new wallpapers...". I created a new user, created therein a 2nd Activity, & switched back & forth between the two. The A/M's thumbnails stayed blank black for both, just like in my "real" user account, & also in a VM for testing. As i said originally, this fault was NOT present in 5.7.5; it came with 5.8.0. Good luck -- i do hope you can identify & solve the root cause. -- You are receiving this mail because: You are watching all bug changes.
