You can solve the flashing panel after weather update.
Go to your aircraft panel.cfg.
Below the main panel section, add the line :
“render_3d_window=1”
Example:
[Window00]
file=mainpanelpic.bmp
size_mm=1024
window_size_ratio=1.000
position=0
visible=1
ident=main_panel
render_3d_window=1
window_size= 1.000, 1.000
