A few of you will have run in to this issue, in Project Web App both in Project Server 2013 and Project Online. In some drop downs we have a transparent background which makes it difficult to read the list of choices as the text behind is also visible, The example below is choosing a custom field at the task level – and the custom field is based on a lookup table. You will also see similar behavior in other areas of the product – such as using the force in/out option in the Portfolio feature. For those of you using Project Server 2013 on-premises you have the answer – the fix was shipped in the April 2013 Cumulative Update – see the second screen shot. For the users of Project Online this same fix will be deployed over the next few months (June-July timeframe) – so you will see the problem go away soon.
Here is a view of the same thing in my Project Server 2013 installation which is patched to the April 2013 Cumulative Update
One other observation while I was testing this scenario – you do now see the default values set for custom fields applied when you create a new task within PWA – and also at the Project level when creating a new Project via Project Center (although it isn’t shown in the PDP while you are creating – it will be there once the project is created).
I have installed all the cumulative updates available and still having this issue. Is there another workaround?
Same here as Wes. I'm fully patched, but am still seeing the transparent background when I use the force-in / force-out option in portfolio analysis.
