I try to compile with the only patch 0004-Fix-for-group-move-hang-v2.patch.
Build OK; no error messages on terminal.
I started the appimage while compiling CinGG, but had no LV2 errors.
(I have a CPU with many threads and have lots of Ram).
No freeze with (build) or without (appimage) patch...
Thanks for testing .... I'll try few more times on my end (may be after reboot).
Reboot happened, my laptop exhibits same symptom (hang), so I guess this is more software than hardware thing.
Phyllis, can you try v2 patch on Fedora and also 32-bit debian and see how it behaves there?
