"Basic Game Loop" from supplied Win32 template results in invalid window regions after window resize

Before resize:

After resize:

Note the white border on the bottom and and right of the "after image."

I was running into this issue myself and decided to install the templates provided here. Surprisingly, it seems the template suffers from the same issue as seen above. My current workaround is to shift the window 1 pixel back-and-forth immediately after resize, but obviously I would prefer to understand the root cause for why this happens. I am encountering this issue on Windows 10 Pro 22H2 (build 19045.3208). Any ideas would be appreciated, thanks!

Is this a Win32 desktop application or a UWP?

This is a Win32 desktop application

I am unable to reproduce this behavior on Windows 11 (22621) with any of the templates.

I saw a post on reddit with the same behavior reported recently (although my search skills seem to be failing me at the moment). I'm assuming this must be a Windows 10 issue because I can reproduce it immediately with the template linked and no modifications on my end. In my case I'm using Nvidia's 536.40 driver (not that I imagine this to be all that significant).

I also am unable to reproduce this behavior on Windows 10 (19045) with any of the templates.

It could be a bug with some 'value-add' software thing on the system.

Hmm interesting, this is a relatively fresh developer machine, and I don't run "1337-gamer" software that I'm aware of, but I will double check, thanks for confirming.
