UI color picker is gone

My color picker is gone and the window where it is supposed to be shown is just a small mirror of the actual screen. The color picker is hidden behind the actual twinmotion screen which I cannot access. I reinstalled TM, have the latest nvidia driver. I tried DPI scaling and it did not help. I think it started when I installed some windows .NET update....but not sure. Can anyone help?

Hello Florian and thank you for posting :)

Would you happen to know what version of .net you updated to?

I've seen issues with the color picker but not this particular one...

I imagine you're using the latest version of TM?

Hi MC_JUT.

These were the updates:

2022-09 Cumulative Update for .NET Framework 3.5, 4.8 and 4.8.1 for Windows 11 for x64 (KB5017497)

2022-09 Cumulative Update for Windows 11 for x64-based Systems (KB5017328)

2022-09 Cumulative Update for Windows 11 for x64-based Systems (KB5017383)

2022-09 Cumulative Update Preview for .NET Framework 3.5, 4.8 and 4.8.1 for Windows 11 for x64 (KB5017859)

Yes I am using the latest TM version including the recent fix a few days ago and still the same issue.

Thank you

I have been having exactly the same issue. Then suddenly today, when I have gone to take a screen shot to send, it is working again!

Hi there guys, I would love to reproduce this bug.

I'm still trying without any success. If anyone comes out with reproducible steps.

Please let me know

Cheers

MC

Sorry it's taken a while to respond. For me the problem came back very soon after. Here is a screenshot:

I don't have any idea what has changed. I tried installing the very latest Nvidia drivers, no difference.

If I press the Windows start key on the keyboard, both the dialogue and the main window turn into colour pickers like this:

If I switch focus back to Twinmotion, it reverts back to the first image, a mirror of the main UI.

Happy to run ant tests if you want me to try anything?

I’m having the same issue now, weird how when I use the snipping tool the issue is still there but at lease I can see the viewport. I suspect it has something to do with the snipping tool and external display.

I managed to resolve this issue eventually by disabling G-Sync in the NVidia drivers in Windowed mode. It works perfectly now.

Thanks. In my case, it does not bring the color picker UI back permanently but at least I see the menu (when using the snipping tool) till I click on it and it disappears again.

Update: So I closed TM after I used the snipping tool and opened it again and the bug was gone...

Not sure but maybe as pauljohnson mentioned the printscreen key could have something to do with it? After I screenshotted TM I got s a short flicker when opening the color picker UI. Although so far the UI remains and does not disappear.

Yes, the same happened to me too. The bug came back.

I forced win11 (the update wasn't available for me yet) to install the 22H2 update and for now, the bug is gone.

THIS IS THE SOLUTION, thank you.
