Yes, a known issue.

I toggle cursorline when needed.

" toggle cursorline or center line
if version >= 700 " NONE turns off underlining
highlight CursorLine NONE ctermbg=Yellow
highlight CursorColumn NONE ctermbg=Yellow
nmap <silent> <F7> :set cursorline!<cr>
else " center line
nmap <F7> zz
endif
imap <F7> <c-o><F7>
vmap <F7> <esc><F7>gv
