Hi @alexkmbk, Thanks for filing the issue. Do you see this behavior happening when running in any specific mode debug/profile/release or all modes? Looks like this happening only on windows 7, On Windows 10 it works fine.

Additionally, you may try upgrading flutter to 2.10.4 and see if it helps fix the issue.

Hi @maheshmnj! I have tried both on debug and release mode - same behavior even after updating to the 2.10.4 version. However, I tried it on the Windows Server 2012 R2 and it works just fine (without this issue). So probably it is the Windows 7 thing.

[Windows] handle repaint message in FlutterView window (#34306)
563d3b0 
This PR will fix the blank FlutterView issue by handling the repaint message in FlutterView window.

Currently, WM_PAINT msg is not handled in flutter window and the default WindowProc will do nothing but paint the background. In some user cases, e.g., hide/show/min/max the app window, this can result in blank FlutterView if the content is static and there are no running animation.
