Chrome 71 no se puede hacer clic después de algún tiempo: se bloquea al arrastrar y soltar un enlace

Desde hace dos días, mi Chrome deja de funcionar después de algunas horas.

Todas las ventanas de Chrome que se abren ya no reaccionan a los clics.

Noto que en el momento en que deja de funcionar, aparece un pequeño cuadro gris que, según

xprop $win_id _NET_WM_PID

parece pertenecer al árbol de procesos de Chrome.

Mi teoría es que Chrome intenta abrir un modal que no funciona y ya no me permite hacer clic en nada en las otras partes de Chrome.

¿Cómo puedo depurar y arreglar eso?

Puedo reproducirlo en algunos casos. Parece suceder cuando arrastro y suelto un enlace a otro lugar. Pero a veces es reproducible a veces no.

He activado el informe de fallos, pero no se ha registrado ningún bloqueo.

Cualquier ayuda para depurar esto es apreciada

Parece que actualizar el controlador de gráficos de Nvidia resolvió el problema. Hasta el momento no hay accidentes desde entonces. Seguirá probando. Deséame suerte.
