Re: Multiple windows get corrupted

Ok. So as expected it happened again. And I followed the steps you (Bram) mentioned. I have following diffs between the bad (left side) and good (right side):

columns=258   <-----> columns=120
lines=72   <-----> lines=60
modified   <-----> nomodified
scroll=35   <-----> scroll=29
window=71   <-----> window=59

lines, columns, and window are set in my .gvimrc. I am experimenting with commenting them out to see if any effect. 

Any ideas from your side?

Thanks.

Perhaps a window resize event makes Vim recompute some things and then
it works again? Just guessing.

If some option gets a wrong value, such as 'lines' or 'columns', that
would cause display errors. You could do the following:

redir > /tmp/settings_1
set! all
redir END

Do this when everything works OK and later when things are wrong, using
a different file name. Then compare the output and try to spot the
difference. If you see an option with a suspect value, you can possibly
find out where it was set with e.g.:

:verbose set lines?
