    Unreal Engine 4.12.5 completely broken due to UI bug.

    Hello all,

    I am a new member here and this is my first post. This may likely not be the correct place for this question. Admins please bump this if needed.
    I am in deep trouble freinds. I need your help. Over a year ago, with great risk and trust I started development on my first game, a virtual reality title called 'Saving Sam'. I am really proud of the progress I have made and have an amazing game to show for it. The main gameplay elements are there, and so is the scaffolding for the levels and story. It really is just about hammering home all the final assets. Even though I am fairly new to development and have no project management tools I've been careful to make backups and have for this entire time avoided creating any major bugs I could not fix on my own with some google searches and some testing.

    At the beginning of this year I reluctantly had to take freelance work because I was running out on money to complete my game. Before going off to the new job I did several backups and test builds of my game. Everything was running wonderful and I set my computer to sleep for a few months.
    When I got back I saw the computer had done some updates. There was an issue with performance because Steam had set screen size to 178%. I fixed that and the game seemed to be fine.


    But when I started to try and work in the engine that's when I realized the Unreal engine itself did not survive the updates.
    Specifically there is a bug in the UI that makes the engine totally unusable. When I activate any pop up menu within blueprints or in the material graph it is dog slow. For instance if I go into a material graph and drag a line from a node, the pop up menu takes several seconds to load. This is even slower in a blueprint graph. Additionally dragging the slider bar, or typing context sensitive searches in the pop up also are very very slow. This is not project specific. All my projects and their backups, as well as blank projects are effected.
    [Oh wow and as I was looking to double check the vertion I realized none of the menu items drop down anymore. Just click and nothing, file, edit, windows, help, all dead.]
    There is no way for me to work like this. I really need a resolution because this has haulted all work. I am in nightmare terriorty. Someone wake me up from this.

    Here is some information I can provide:
    Unreal engine 4.12.5 (migrating the project to a different version is not ideal at this stage)
    win 10 version 1803
    I do not have nvidia experience active, gamebar is off
    intel core i7-6700K @4.00GHz
    32 GB

    Thank you for listening,


    Justin Lloyd

    PS- why in the F&@! does windows give me no option to turn off updates!

    Hey Justin,

    First thing I would try is to open up the launcher, click the small down arrow next to the Launch button for your engine version, then click Verify. There shouldn't be any reason the files would become corrupted if you haven't used the engine for a while, but you never know. Here's an image showing what I mean:
    Click image for larger version  Name:	verify.JPG Views:	1 Size:	58.0 KB ID:	1488205

    If that doesn't help the next thing to check is your video card drivers, make sure they are up to date and do a clean install (use the Custom installation button, there will be a checkbox on the next page for Clean Install).

    Another thing that might be worth trying (unless you are using 4.12.5 for a reason) is to download a more recent version of the editor, create a copy of your project, then try opening that copy in the newer engine version.

    Hope one of those help!

      Thanks for the reply,

      I am pretty sure the engine is intact. It is something to do with one of the Win 10 updates causing a conflict. People were having a similar problem months ago because they had creators option turned on in win updates. I must have gotten that update now. Only problem is those threads seem to have dead ends. I don't see any solutions to the issue.

      I cannot go to a higher version in Unreal. If you look at the compatibility Epic must have made some major changes because most assets created in 12 do not work in 13 or later versions. I have a lot of assets in the game already. I could try that, but it really is a major overhaul and round of testing all levels and assets of the game for what seems like a small bug I should be able to fix.

      I can try and update my graphics driver though I don't think it's going to fix this. Unless anyone has any other information about this issue that is the only thing I really can try at the moment.

        Using Windows High Contrast mode seems to solve the issue with the drop down menu not displaying. I had the same issue while working with the VRFunHouse and it worked.

          Thank you. That led me to a solution! It seems to work now. This saved me so much headache.
