MMNoTitleBarWindowKey for hiding titlebar

[splhack]

$ defaults write org.vim.MacVim MMNoTitleBarWindow true

but it's not finished yet, needs to fix the error.

ERROR: Can't have a toolbar in a window with <NSNextStepFrame: 0x7ff618f46a20> as it's borderview

It works. There seems to be no way to move a titlebar-less window all the way flush against the right-hand edge of the screen. I have an ineliminable gap of about fix or six pixels.

I've tried enabling this on 10.12.1 and it does remove the titlebar, but it causes text rendering problems. The screen is gray, and any typing appears for a moment, then disappears.

I did notice that if I disable core text rendering, it does work, though I'd rather not do that.

I'm experiencing the same problem as @bensinc. Any clue on that?

[KCreate]

Same problem as @bensinc. Are there any updates on how to fix this issue?

[cmcginty]

Thanks for this so much! But when I enable this feature the window eventually turns all white. Is there a setting that might conflict with this value. Thanks for the help! Testing on Sierra 10.12.6.

Same problem here.

macVim 8.0.1420 (144)
macOS 10.12.6

Still Broken. Bump.

[omartin]

Broken, can be better by removing the CoreText but still there is a white line at the top.

@splhack finding this PR and knowing this exists made my day.

[mirca]

@acidjazz it exists, which is super cool in itself (thanks @splhack); but does it work?

[acidjazz]

@mirca works fine for me, just pasted it into terminal, started up macvim, and no more title bar.

[mirca]

yo everybody, it's working!! @bensinc @whiteShtef @omartin @jampow @cmcginty @KCreate

Yes this should be working! In 10.13 or below it was fixed in #828 but the no-titlebar / borderless mode has some performance issues compared to normal windowed mode. In 10.14 it should work just like the normal mode.

[sbrki]

Woohoo! Thanks for implementing this.

found this totally by accident - makes me so happy. Thanks so much! 🥰
