Do you use multiple monitors?

Do you use multiple monitors?

Yes

There's a known issue about window positioning when multiple monitors are used: #420 #452, I might able to look at it this weekend.

A possible workaround is to switch primary/secondary monitors.

OK, Thank you😃

Could you try https://ci.appveyor.com/project/xupefei/quicklook/builds/35688242/artifacts and confirm the fix?

I try and it's wired that when I view a pdf, the windows top-bar is hidden as the follow picture, when I switch to another pdf the position has changed, but the code file is normal display.
In the old version I used the pdf view is also normal.

Yep, the "fixed" build shows the same behaviour as Airloss just replied about on my setup as well.
Primary display 2736x1824, 200% scaling
Secondary display 1600x1200, 100% scaling

On the larger primary display, the QuickLook window cuts off at the top of the screen when it's displaying something large like a PDF or image preview, but it always works flawlessly on the smaller secondary display.
I also tested switching the primary/secondary displays around (and signed out+in again just in case), and even when I have the smaller display set to primary, it works great like before, but on the larger display (secondary) it still cuts off the top of the screen.

How about this one then: https://ci.appveyor.com/project/xupefei/quicklook/builds/35688332/artifacts

I have tested several types of files and they all display normally in my multiple monitors.
