HVM window frozen after resume


I installed a debian-based version (PureOs) in HVM on Qubes 4.1 on a librem14. Everything works fine, but:
After resume from Qubes suspend, no way to get the HVM window respond again. It is frozen. All other VM are working.
If I open a console for the HVM, i can do anything with it, so I think it is a GUI problem.
I need to restart it to get the window work again.
