Research direction

Start at crates\egui_glow\src\painter.rs:439 in paint_mesh and reproduce the demo app on Windows 10 after closing and reopening the notebook lid. Use the console's GL_INVALID_OPERATION report and attached screenshot to establish the failing state; completion requires identifying and fixing the cause, with verification that the error no longer occurs.
