Neovim periodically emits wrong window title if title option is set

[Nimmidev]

Recently i enabled the title option so my polybar on linux would display the current edited file.
For some reason i noticed a flickering in the title when i was typing.
Running xtitle -s to inspect title changes revealed that every so often neovim would emit a wrong title for a split second which caused the flickering.
Here is the output while editing a file called test.sh in /tmp:

test.sh (/tmp) - NVIM
test.sh (/tmp) - NVIM
test.sh + (/tmp) - NVIM
test.sh + (/tmp) - NVIM
[No Name] - NVIM
[No Name] - NVIM
test.sh + (/tmp) - NVIM
test.sh + (/tmp) - NVIM
[No Name] - NVIM
[No Name] - NVIM
test.sh + (/tmp) - NVIM
test.sh + (/tmp) - NVIM

After hours of adjusting my config, enabling and disabling plugins. It seems that cmp-buffer causes the issue.
With the default nvim-cmp setup everything works fine without the buffer source. But as soon as buffer is added to the sources, the [No Name] - NVIM titles start to appear.

My nvim version:

NVIM v0.7.2
Build type: Release
LuaJIT 2.1.0-beta3
Compiled by builduser

All plugins are on the latest version.
