Still have the issue with 0.6.12. It is slightly different in that there is now no window frame (border) at all. Before there was an aero-like window frame. The application's client content (UI etc.) is drawn as expected but nothing happens when clicking File or the menu buttons.
This is different from #18. I'm on an Intel GPU and I see much more than an empty window.
Intel Core i5-5200, HD Graphics 5500. But I don't think the problem is GPU related. It's Windows 10 related. If I tell Windows to run the program in compatibility mode for Window 8 it works fine. I can operate the program via keyboard commands when not in compatibility mode. It's just the GUI controls that don't work.
The aero-like frame is still there, after all. Not sure why it didn't appear one time. Here's the image.
I have released a new version of PicoPixel (0.6.13). Unfortunately, I believe there is an issue with the Intel graphics driver that prevents from resolving this issue in a way that does not affect the appearance of PicoPixel. So, for the moment PicoPixel will automatically show the window frame when running on an Intel HD GPU.
All the features of PicoPixel are there. Only the window frame has changed. When running on a Geforce or Radeon GPU, PicoPixel appearance is unchanged.
