[Daniel van Vugt (vanvugt)]

Do you have an external monitor connected when the problem happens? I am reminded of bug 1872159.

[Michel-Ekimia (michel.ekimia)]

the several clients had this without external screen but I mark it anyway as a duplicate of 1872159 , as it seems to happen also less often to some people without external screen
