Issue with Rstudio version (Version 1.3.1073) "Giant goldenrod" when moving R studio window to new monitor doesn't display correctly

Question

This is a basic question that I hope has a simple solution. When I move my Rstudio window to an external monitor display - it no longer rescales properly and instead is rendered completely useless - showing me only the lower portion of the window (see screenshot) and doesn't allow me to resize the window or adjust it in anyway to access the taskbar along the top. Has anyone else experienced this or have options for how this could be fixed?

I frequently need to shift my Rstudio window to different monitors, and I was doing this with no issue prior to installing the latest Rstudio version - so I am wondering if there must just be some setting that got reset when I updated the software, but I can't seem to figure it out. I have tried fixing scaling options in Windows by using the properties options on the Rstudio icon on my desktop - and then clicking on compatibility and High DPI settings, but messing around with that so far hasn't seemed to work. However I haven't tried all possible combinations as i thought I would check here first to see if someone could fast track this process for me. As you can see in the image - this display is impossible to work with. When I move it back - it works as it should. I am using Windows 10, and I update my software regularly. TY!

Update

Ok, I was able to reproduce on a Lenovo with an external Dell monitor and address the problem by applying a fix proposed in another Stack Overflow thread. See below:

Research: https://support.microsoft.com/en-us/topic/windows-scaling-issues-for-high-dpi-devices-508483cd-7c59-0d08-12b0-960b99aa347d

Resolution:

There is a solution, it comes from the option "Compatibility" of the execute file.

• Close all current RStudio windows.

• Right-click on the shortcut of RStudio (or the original .exe file) and choose Properties

• 

• In the RStudio Properties pop-up windows, choose the tab Compatibility

• Select High DPI settings

• 

• Tick on option Override hide DPI scaling... and then choose System from the drop-down list.

• 

• Apply > OK.

• (Re)open Rstudio to see the change

On my test system, this addressed the problem observed where the menu text became super large.

Stackoverflow original reference:

• RStudio HiDPI support

This appears to be an issue with the version of QT used by RStudio. RStudio is built on top of the QT engine.

QT tracking Issue:

https://bugreports.qt.io/browse/QTBUG-48242

the issue is marked as fixed in QT version 5.9.0 and above.

Recommendation:

Download RStudio preview and try that:

https://www.rstudio.com/products/rstudio/download/preview/

Why? The preview version of RStudio appears to use QtWebEngine/5.12.8, which implies the issue is addressed. If that does not resolve the issue you could file a bug with RStudio, or install and recompile RStudio from the source with an updated version of QT. You can check your QT version via the help, about box.

Hoping the above points you in the right direction. Stays safe and well.
