Background erase colour not updated when restoring cursor #328

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Run a fullscreen terminal program such as vim that has a different color 
that the terminal (example, my terminal has a purple background, vim has a 
black background)
2. Exit the program
3. Colors will mess up in certain cases now. For example, backspacing 
characters. Or opening a man page.

What is the expected output? What do you see instead?
My terminal background color should be all I see. But after doing this, I 
occasionally see the alternate color (black instead of purple)

What versions of mintty, Cygwin/MSYS, and Windows are you using?
mintty 1.0.3
cygwin 1.7.11

Please provide any additional information below.

After a bit more playing around with it, this only seems to happen when I quit 
vim using
:q
if I write a quit (:wq), the colors are fine.

I can't reproduce that, either with default vim settings nor with syntax 
highlighting enabled.

Are you using a particular colour scheme? Maybe that has a bug, leaving the 
background colour set to ANSI black instead of the default background colour on 
vim exit. You could work around it by having your prompt reset the colours. 
Cygwin's default bash prompt does just that.

I'm not using a particular color scheme to my knowledge. I admit I may be doing 
it wrong, but I had just set the background of vim to black manually in the 
.vimrc file.

However, I looked up Cygwin's default bash prompt and stole the relevant color 
reset portion of it (I'm not fantastic at those control sequences), and 
everything works. It's probably my fault for setting the vim color incorrectly 
or something.

Thanks and I hope I didn't waste too much time.

No worries. How do you set the background colour in .vimrc? (I want to make 
sure that mintty isn't behaving differently from xterm here.)

relevant .vimrc lines:
hi normal ctermbg=black
set background=dark

my .vimrc is otherwise unmodified from the stock cygwin install.

I also can confirm this behavior. My terminal's background is black (default), 
but I use a Vim theme with a bright background. If I quit Vim with :q, then 
clearing the screen (with clear or <C-l>) in the terminal leaves its background 
bright (the same as my Vim theme's background color). If I quit Vim using :wq 
then all is fine.

One thing I should mention is that I've set my term to be xterm-256color in my 
.mittyrc.

This doesn't happen in xterm, nor in PuTTY. It happens in mintty when new lines 
are scrolled in from the bottom. Apparently I introduced this bug with mintty 
0.6.

Fixed in r1263 on 1.0 branch. I introduced the problem in r826 on the 0.6 
branch, wrongly dropping the update of the erase character's attributes when 
restoring a saved cursor.
