permanently 100% cpu

In my terminal (Konsole on NixOS 19.04) tig uses 100% cpu permanently. It is responsive and works well, but the 100% is not normal.

perf record -g tig

Running tig from console (not X) does not give 100% cpu. Running via ssh or as sudo tig also does not give 100% cpu. Running with minimal env variables in X (env -i PATH=$PATH TERM=$TERM tig) gives 100% cpu use.

Does it still happen after 38c54de739c9752d5107288db0d5a6ca48efdd31 ?
