When using a "Change size of text, apps and other items" setting other than 100%, when in fullscreen on Minecraft, the cursor position differs from the actual mouse selection position. Changing the setting back to 100% resolves the problem. Resolution during testing was 1920x1080.

Is this still an issue in the most recent versions (currently that is 1.10.2, or 16w44a) of Minecraft? If so, please update the affected versions and help us keeping this ticket updated from time to time. If you are the owner/reporter of this ticket, you can modify the affected version(s) yourself.
Problem is occurring on Minecraft v1.11.2 (java version 1.8.0_25) on Windows 10 on a 2560x1440 screen. "Change size of text, apps and other items" setting is at 125% (recommended as per Windows).
In windowed mode, the cursor is perfectly aligned with the selection.
In fullscreen mode, the cursor is misaligned. Cursor on Multiplayer selects Singleplayer, you have to be a bit to the right of the start of the button.
Changing the setting indicated by initial report to 100% fixes the issue but that makes the overall Windows interface harder to read and would probably be even worse at higher resolutions.
The problem started occurring today and situation was not present since the 11.1.2 update. No specific change/installation performed since the start of the issue.
All other games are fine. Minecraft only issue.
Reporting back on this. Computer has since then been rebooted and the issue has disappeared.
Thinking of it I believe that a previous issue with the displayport having been re-inserted more firmly in the monitor so that it would stay in place may have caused an issue with the GFX card/drivers in terms of supported resolution knowledge. Very weird though as Minecraft was the only application to have an issue.
I've just observed this and I know why it was hard to reproduce. As soon as you log out or restart the computer the problem goes away.
It's a bug that only shows up in fullscreen when there is a pending DPI change.
Repro steps:
Set the system DPI to 125%
Log out of Windows
Log back in
Set the system DPI to 100%
Start Minecraft
If not in fullscreen, switch to fullscreen
Observe that the mouse cursor position does not match the highlighting on the screen
This pending-DPI behavior is totally a resolvable problem.
Just got emailed about this now.
The mouse position is no longer an issue. What is a new related issue, if you follow the repro steps I have, is that the Minecraft window chooses the wrong fullscreen size:
[media]Again, this is when you've changed the DPI but haven't logged out and back in yet.
A separate note: the reason I was adjusting the DPI in the first place was that Minecraft's fullscreen mode was making the window 1.25x too big when I was using my normal 125% DPI.
Now it's not doing that any more, so I have no reason to fiddle with the DPI settings. But regardless, Minecraft should work after adjusting the DPI without you having to log out and back in. That's still an unresolved issue.
Someone forgot to check if windows was automatically resizing their crosshair...
I have not tested it yet.
I recommend you put your java version in the environment as well.
