I tried reproducing the problem with the following test, but it did not appear with meld 1.16.0:
perl -e 'for ($i=0; $i<4000010; $i++) { print "$i\n"}' > test1 && (cat test1 && echo "end") > test2 && meld test1 test2 Could you please reproduce the issue with this test case? Could you please reproduce the issue with meld 16.0?
