I've been dealing with this issue
for a while, but never submitted it as a bug:
So here's a few themes that indent child tracks (
NotMyFault minus minus,
Symbiosis, and
ReaLax):
The problem occurs when you hide a child track in the TCP, but keep it visible in the MCP (done via Actions:
Track: Toggle show/hide in TCP, or
View > Track Manager). Initially it behaves how you'd expect and still looks like the above 3 screenshots. However, upon closing and re-opening Reaper, any tracks that are hidden in the TCP will no longer be indented:
I'm not sure why WALTER thinks the folderstate has changed and I can't seem to figure how to fix this.
