hi,
I've got broken TUI output for "perf report --group"
Samples: 17 of event 'anon group { cycles, instructions }', Event count
(approx.): 9145256
56.44% 31.59% ls libc-2.17.so [.] __strcoll_l
39.94% 0.00% ls ld-2.17.so [.] _dl_new_object
3.48% 0.00% ls [kernel.kallsyms] [k] setup_arg_pages
0.14% 0.33% ls [kernel.kallsyms] [k] native_write_msr_safe
0.00% 30.17% ls [kernel.kallsyms] [k] security_inode_permission
0.00% 29.78% ls ls [.] indent
0.00% 8.12% ls [kernel.kallsyms] [k] __slab_alloc
I have 'show-headers' set to false in ~/.perfconfig and the output
got fixed after displaying headers by pressing 'H'
