This issue affects all environments. The example in this post is from the Lagoon environment.

This is what the block menu used to look like prior to the VR update.

This is what the block menu looks like as of today, 4/22/2016.

Is this a bug, or an intentional change? Personally, I prefer the previous menu layout to the current one.

Here are my system specs:
3.6 GHz Intel Core i7 4790; 16 GB RAM; DirectX 11; GeForce GTX 960
Windows 7 Pro x64; Single user (admin)
Local Area Connection, 100 Mbps; Google Chrome
Default.SystemConfig.Gbx
HQWindow.SystemConfig.Gbx (my current custom configuration)
