Thanks Scott. As far as I can tell, this bug isn't 4k specific.
If I change my 1080p monitor to have the same scaling factor as the 4k
monitor and drag TortoiseHg across the problem does not occur. The bug
seems tied to different scaling factors, regardless of the monitor
resolution.

I don’t have a 4k monitor, but I will try to play with it on a
multimonitor PC and see if I can set the scaling factor on one screen
and not the other (all three screens are the same resolution here)
There is not (that I know of) a QScintialla public test app

It just tested SciTE and it works fine.
Do you have an equivalent program that uses QScintilla?
PS: Using TortoiseHg, if I keep the application on the same monitor
and change its scaling factor the bug does not occur. The bug only
seems to occur when the application is dragged from one monitor to
another. My guess is that when the application is sitting on one
monitor and the scaling factor is changed, it receives and responds to
an event. But when the application is dragged across monitors it does
not recieve a scaling-specific event and as such it doesn't think to
update the DPI accordingly. I would be surprised if this logic was
TortoiseHg-specific (it seems like something that should be handled by
the lower layers) but who knows...
Thanks,

Understood.
You may want to try SciTE.
That is a base editor, tied to the core Scintilla widget, not used
QScintilla (which is a Qt wrapper for the core)
In reality, the TortoiseHg devs, need to work on this, to see if
its their bug first..
This could be due to the 4k to HD resolution swap…

Hi Scott,
I'm not affiliated with TortoiseHg. I'm just an end-user. As such,
I have no idea how to create a minimal testcase outside of
TortoiseHg. When I filed a bug report at
https://bitbucket.org/tortoisehg/thg/issues/5086/caret-position-is-incorrect-if-window
I attached a video demonstrating the problem. Hopefully that'll help.
If you guys have a stand-alone application I could run, I can try
reproducing the problem with it as well.
Thanks,
Gili

However, looking at the issue, there is no minimal testcase.
There is also nothing saying it’s a bug in Scintilla,
QScintilla or tortoisehg. It could be any of the three.
Why is the assumption being made that its QScintilla?

Hi,
Can someone please take a look at this bug report
which seems to affect your project?
Sorry, I don't have the equipment needed to reproduce the
problem.

Hi Phil,
Which equipment are you missing? A video card with 2 ports? 2
monitors? Or a copy of Windows?
...and a PC.
Phil
Fortunately for you, that's not a problem :) Assuming you have
a Mac laptop:
1. Plug in a second monitor (any will do) so your laptop sees
multiple monitors.
2. Fire up a virtual machine of your choosing. I used VMWare
Workstation, which is equivalent to VMWare Fusion on Mac.
I believe VirtualBox (which is free) will work just as well.
3. Download and install the Windows 10 ISO which you can
download for free from
https://www.microsoft.com/en-ca/software-download/windows10
4. You can run Windows 10 without a license for a short
period of time (30 days I believe) so this isn't a problem.
5. Configure the VM with 2 virtual monitors and you should be
able to reproduce the problem.
6. I just tried it in VMWare Workstation and it worked for me.
I haven't been able to get this working (yet) using a single
physical monitor. See
https://superuser.com/questions/1325393/how-to-use-multiple-virtual-monitors-if-host-has-a-single-monitor
But it's possible that VirtualBox is better in this regard
than VMWare Workstation.
