After installing VB 5.1 I have problems with Text Selection pointer that it is quite invisible.
Could it be related to scale factor?

Thank you

Please read the following: Minimum information needed for assistance.

I have a WIn10 x64 (32gb) as host and WinXp SP3 as guest (4gb) + guest addition.

You replied to the first two bullet points. The third one is the best of them all. For the VM log file ("VBox.log.zip"), here's what you do:

1. Start the VM. Not from a saved or suspended state. Clean start.
2. Take the steps required to generate/observe the error.
3. Record the error message. EXACTLY. Post a screenshot if you have to.
4. Shut down the VM (if it hasn't aborted by itself). Not suspended, not paused. Shut down. If you can't shut it down by normal means, close the VM window and select "Power off".
5. Right-click on the VM in the VirtualBox Manager.
6. Select "Show Log..."
7. Save it (just the first log, VBox.log), ZIP it and attach it in your response (see the "Upload attachment" at the bottom of the form).

logs are attached, but nothing is visible...

In my opinion it is a graphical issue related to screen resolution, but I'm not able to find a way to fix it, and it was not present in previous version
thank you for your support

I didn't immediately see anything weird. Maybe someone else will. At the end it might simply be graphics artifacts. You have an Intel graphics card that has been know to produce issues like that (generally speaking).

You could head to the bugtracker and either search for an appropriate bug where you'll attach your logs and other vital information, or open a new bug report.

I can confirm that the problem is related to guest additions: removing that everything works as expected.
