double window title on Windows

Screenshot
Windows 10
GoNeovim 0.4.3
And clicking the lower window title bar, instead of tabs, responds to tab switching

Hi :D
Thank you for your report.
What your windows 10 revision? (1803, 1809, 1903, etc)

I've also seen this problem only when opening a markdown file.
I have also confirmed that Windows10 1903 does not cause the problems, and 1809 have the probrem.

I have the same issue, the display is a bit different, as the upper window title
isn't even displayed but pure black.

I use Windows 10 1809

I tried to reproduce it on my home virtual machine Windows10 1809, but could not reproduce the problem.
So I think the problem isn't OS-dependent, but something else.
I will continue to investigate, but the investigation has been difficult... 😵

Hi
Is your environment a physical machine, not a virtual machine?
I've investigated this problem in some environments and it seems that the problem isn't happening with virtual machines, so I want to test the hypothesis.

@bon-ami @Sh3Rm4n
This problem has been fixed in v0.4.4
Is it possible to confirm the problem?

[Sh3Rm4n]

Thank you for your work on this! I do not have my Windows machine available until Monday. I will try the new version then. Disclaimer: I updated to 1903 last week, so if it works, I can not say if it is, because I updated or you fixed the problem or both. I had difficulties before reproducing this issue, that's why I did not deliver any more info on this.

Nonetheless, thank you for your effort on this :)

I played around a bit with version v0.4.4. Resizing, opening new tabs, opening and closing windows and so on. And as far as I can see, the title bar stays at the expected position and the icons line up with the mouse-clickable area. So at least for me, it seems like it is fixed :)

[akiyosi]

Thank you for confirmation.

I have confirmed that fixing this problem causes a side effect. I have confirmed that when I perform the following operations, the application window temporarily stops updating the screen. I am currently analyzing this problem.

1. Change window size
2. Minimize window
3. Restore windows from taskbar

[Sh3Rm4n]

I can confirm this.

I fixed the comment #91 (comment) in v0.4.5. But we're still seeing edge cases that have problems...

When opening the Markdown preview on Windows, the command history content is missing in the external command line (Extcmdline = true).
