Package: xterm
Version: 398-1
Severity: normal

Dear Maintainer,

Sorry, this is probably a terrible bug report, but I figured that I 
should let you know that I have had intermittent glitches with xterm
for a while now.  It forces me to use a different x-terminal-emulator, 
as I can't trust what is on the screen.  Feel free to reject the bug 
report if it provides no value. Happy to provide any additional debug 
info.  I reviewed both 463784 and 1014625 but I can't tell if it's the 
same issue.  It seems scroll related.

I observe the issue most often when I try to compose a message with mutt 
+ nvim, and when I press enter, the following line is duplicated each 
time. The glitches are cleared on the screen with ctrl-l but the issue 
persist.  I have also seen it with nvim editing a text file.  I have 
eliminated mutt, nvim, and tmux.  I have seen it with both vim and nvim.
I also seen it a strange scroll behavior half way down the screen.

If I open a 2nd xterm when I see the issue, it too, will exhibit the 
same issue, as will closing and retrying.  Then I installed alacritty, 
and when I started it, the glitches in xterm disappeared.

I have been on the same hardware for years, NVIDIA Corporation GM206GLM 
[Quadro M2200 Mobile], and been tracking the stable driver.
