I just found this in dmesg (it appears every time I start a Steam game), pretty sure it is connected: gameoverlayui[6032]: segfault at 0 ip 00000000f702b619 sp 00000000ffe0d7c0 error 4 in gameoverlayui.so[f6ef4000+45a000] If anyone has any idea how to investigate into this more future please share.
