I have a program written in lazarus running normally in windows 7. When run in windows 10, the green color of the Frame/Form is changed by Windows 10 to white.

Now my customer is complaining the bright white is hurting his eyes.

Can anyone help? I googled and the only articles is about changing the title bar color, not the form's color.

My best suggestion is to encourage your customer to downgrade to Windows 7. Hewlett Packard, when you select a professional grade laptop or desktop, as of today is still providing Windows 7 professional preinstalled, and includes an upgrade DVD to Windows 10, which you may decide to use, but at your own risk. They know better!

Hi,

I can't confirm that for Windows 10 1610 32bit with Lazarus 1.6/ FPC 3.0 and Lazarus/FPC Trunk. Form shows colour correctly (see pic) and frame seems to be transparent.

Maybe a TPanel can help.

Yeah right - that will never happen! All that effort just for one application, because LCL doesn't support the most basic of theming.

This works here: When I set the Form1.Color to clGreen I see green background on Win10.

Can you reproduce this in a small example program so that differences regarding the project settings can be avoided?

Attached is a simple test project. Within the zip are 2 screen capture of the same program running in win 7 64 bit and Win 10 64 bit. The project was created with Lazarus 1.7; fpc 3.1.1 SVN 52643.

Thanks so much for help.

For me, the frame is white in both Win7 and Win10. Did you deactivate themes in Win7? Your screenshot looks like this. This would switch to the old Win95 style, and give you back control over the color of many controls. In Lazarus, you can turn theme support off by unchecking "Use manifest file to enable themes" in the Project Options. This works also in Win10 - see attached screenshot:

Yes, I disabled themes in win 7 (and forgot about it). Thank you so much. It worked after unchecking the "Use manifest file to enable themes".

It would be even better if the options can be changed in runtime so that users can decide whether to enable themes.
