Meld hang only when running with X11 ssh forwarding on Ubuntu 18.04
Meld runs fine on the native screen of a Ubuntu 18.04 box. But when I run it on a ssh terminal with X11 server (cygwin on Windows), the window popped up, but meld just hang, with a circle spinning forever on the top right. There is a red stop button in the middle, but there is no use clicking it. There was no rendering of the difference between the two files. The text files are simple ones, no more than 200 lines long.
Again, when I run the same command natively on the same Ubuntu 18.04 box, it runs fine.
