I would say a SWT issue. In this context Console is not much more than a StyledText. If I open a large file (e.g. StyledText.java), enable word wrap and resize the editor I see very similar results to a console with same configuration and 10,000 lines of output (even if non need to be wrapped). Is there something special with your console output? Unlimited output, how many lines, very long line (afaik even with word wrap enabled StyledText is not very happy with long lines). Apart from that you might try fixed width console instead of word wrap which is significant faster in my experience.

Very, very long line, the language server returns 16 million chars in one line. :-o > Apart from that you might try fixed width console instead of word wrap which > is significant faster in my experience.
