An IE 11 problem on displaying tabs of a report on report manager

Problem:

I created a report using report builder 3 and saved it to report manager. However, when I view the report on report manager, I noticed that tabs are in separate rows as shown below. Notice: Show tabs in a separate row" is off.


Solution: 

Uninstall IE 11 and resort to IE 10. It works as expected as below.


Another option is to add the URL (http://localhost/) to the compatibility view. You can find the option as below.


Several parts do not show up on Dataset Properties in Report Builder 3

Problem: 

After the dataset is created, the next step is to create a dataset. Both are embedded in my case. However, I notice that three buttons (i.e.,Query Designer, Import, Refresh Fields) are missing under the query box on the Dataset Properties panel in report builder 3 as below.


Reason: 

I had customized my desktop to 125% at one time, which causes the three buttons not showing up.

Solution: 

Set the display to 100%.
