It is now fixed in R-devel 82776 (it would be nice if you could confirm the problem is fixed for you on your system). You have run into an old bug in GraphApp, a library used by Rgui. The part saving and restoring the preferences works fine, but the problem occurs on R startup when creating a new console window. Rgui computes the client size of the window based on the preferred number of rows and columns and asks GraphApp to create such window. GraphApp uses its internal code (probably it pre-dates AdjustWindowRect) to compute the screen size of the window, so including the title bar, scroll bars, etc, and then asks Windows to create the window. Rgui then checks the actual client size of the created window and updates the number of rows and columns based on that - which is also the number you then see in the preferences editor. Ideally/normally it should be the same as what was given initially, e.g. via Rconsole. However, the computation in GraphApp didn't work quite right, it didn't account for the scrollbars. And the reason was that it assumed a canvas (CanvasSize bit was set on the window flags). That bit was set by accident, because GraphApp by accident used the same bit number for CanvasSize and UseUnicode. The UseUnicode bit is set in Rgui when running in a multi-byte locale, so for you and many others probably only since R 4.2. I've changed GraphApp to use a different bit. Thanks for testing Rgui and reporting problems.

[Rd] Mismatch between the Rconsole file and the RGui Configuration editor
Dear Tomas, Thank you for your attention and for the detailed explanation about the issue with the R Gui. As you have indicated, I tested R version 4.2.1 Patched (2022-08-30 r82776 ucrt), which I downloaded today. Unfortunately, the mismatch between the Rconsole file and the GUI preferences continues to happen here on my computer. Even if I delete the Rconsole file from the Documents folder in Windows and save a new Rconsole file, there is that mismatch. It seems that the GUI editor (and the actual size of the R worspace) is always a bit smaller that what is recorded in the Rconsole file, that is, a bit smaller than what I specified for rows and columns. For instance, if I specified 37 rows and 112 columns, this is what is recorded in the Rconsole file, but when I open R and go to the Gui editor, I find 36 rows and 110 columns, and the workspace is clearly different from my specifications. I use Windows 10 Pro for Workstations, version 21H2, installed on 23/?August/?2022, build 19044.1889 (this is the latest update for Windows 10). As I said before, of course the mismatch does not prevent me of using R, this could be said to be just a nuisance. But I think that no mismatch should be happening. Thank you once again.
