See #11743 for a well-argued criticism of company-dabbrev's tendency to over-zealously suggest useless completions.
With many buffers open, many of the completions offered by company-dabbrev can be nonsense. For example, if a magit log happens to be open, then many of the suggested completions may be hashes of commits, and if a PDF is open, many of the completions will be nonsense strings that include control characters.
This PR sets company-dabbrev-other-buffers to t which means that company-dabbrev should only search for completions in other buffers with the same major mode. This should significantly cut down on the noise without going quite so far as suggested in #11743 and removing company-dabbrev as a backend entirely
