black window after un-minimizing

[sdicker8]

2022 build tools
win 11 x64
v9.1.1

When LvglWindowDesktopApplication is minimized and then un-minimized the window is black. When the app is then maximized the window recovers.

I also see #71 -- it seems to consume 100% of one of my cpu cores - the memory seems stable.

Thank you -

Nice project!

I need to do some reproduce work to fix the issue.

Found a solution?

The window needs repainting in full when un-minimizing otherwise only dirty areas will be painted when called.
Maybe use WM_WINDOWPOSCHANGED or similar.
