Hello Josef,
I'm using Sculpt 20.08 (the officially released image). Here's the LOG output:
[runtime] child "cmus" [runtime] RAM quota: 65288K [runtime] cap quota: 466 [runtime] ELF binary: init [runtime] priority: 0
All the lines you've mentioned after [runtime] priority: 0 are not shown.
the Terminal change, where it now uses the gui session directly but in the past used a framebuffer session
I guess this could be the problem.
Best regards, Dima Sokolov
