I have this odd behavior on several Chrome instances that are synchronized over different computers. For a very brief moment (like the 10th of a second), a notification with Chinese text appears and immediately disappears again.
This happens roughly two times a day so there is no way I could wait for it. The time also does not appear to be relevant as the last one appeared four minutes past four o'clock.
I'm afraid this might be malware. I'm running Linux Mint 17 and 18 and the notifications appear on both types of system. My extensions are all trustworthy (I guess).
I already removed all notification permissions but the problem persists. Is there a way to find out the cause of this notification? Like to log notifications to a file or something like that? Thanks.
