Hello.
You can see the illustration of this little issue below.
Is it clear?
As for as I see, it happens on 4K monitors.

Brilliant Ian - thanks for that!

We test LogViewPlus daily on a 4K display at 150% scaling on a multi-monitor desktop.  The application scales well under test, but we do have several customer reported issues like the one above. 

The problem we have is that Windows has a lot of settings which control this behaviour and it is difficult to track down which particular setting might be causing the issue.  As a fail safe, you can now disable scaling, but this causes images to be less sharp.  I have to admit that I am usually focused on the Display settings, so this one often skips my mind. 

LogViewPlus knows how to scale itself, so it makes sense that this setting should always be set to Application.  We plan to put together a documentation page discussing these issues soon and I will be sure to add this setting.

Thanks again,

Toby
