Hi David,

I have exactly the same problem using ssh accessing a machine that is running CentOS 7.3.1611, making it essentially unusable for vi. No problems when I access an older computer running OpenSuSE 11.4 from the same Mac.  I am also using XQuartz 2.7.11, and my mac is at 10.12.6.  Strange.

Any help with this problem would be greatly appreciated.

Thanks

Hi,

I’ve run into an annoyance when using ssh to access a ubuntu system.  When using vi or vim, the screen doesn’t refresh properly when paging forward/backward using ctrl-f/ctrl-b.  What happens is I get a union of non-space characters between the old page and the new page.  So if a character is a space on the first page and in that location a non-space character is on the second page, then the non-space character is written. If the second page has a space, then it doesn’t replace whatever was on the screen from the first page.  On the other hand, if I scroll one line at a time, it works correctly (just annoying if I’m trying to go through a large file).  Any ideas how to fix this?  I’m using XQuartz 2.7.11.  Odd thing is, it only does it on my macs with 10.13, my laptop that still has 10.12 does not have this problem.

Thanks…

David
