Flicker when clicking the start menu #4

The taskbar is flickering for me when I click on things, particularly the start menu.

Here's an example: https://gfycat.com/FluffyWetBanteng

When you click on the Start Button, Windows automatically re-applies the "right" style to the Taskbar. I'm going to try to find a way to interrupt that so there's no flickering, but for now, that's an unfortunate side-effect.

It would require a hook, something not doable in C#, only C++

Elestriel commented 7 years ago

You would be amazed at some of the hooks I've written in C#. ;)

sylveon commented 7 years ago

Depends on the type. A hook for keyboard can be, but a hook for messages, as required in this situation, requires a native DLL library to inject (so it can't be written in C# because the resulting DLL would be managed)

olliecheng commented 7 years ago

Yup. That hook would need to receive the WM_PAINT message.

Let me add that writing such a hook is not for the faint of heart. Both myself and @charlesmilette tried and I at least have given up for now. If you do go down this path, you will want to use SetWindowHookEx. Subclassing won't work as you don't own the Window.

FWIW, in my C++ version I was able to lower the sleep to 5ms without serious repercussions, which gets rid of all flickering I have seen.
