Facebook should know that people generally don't use the 'who's active' window and it is annoying to work when something is constantly updating and re-rendering on the screen. Just fixing this problem would make it a 4 star and a recommend for everyone in the world.Ģ. This is on no other Messenger platform that I know of. I write in a foreign language and as my language is not supported I get red lines under everything I write.

It completely cripped a brand new computer just being open. This is a HUGE issue that Facebook needs to address before continuing to offer this app. I did some more research and found out that many people were also having this problem in both Windows and Microsoft. Immediately, fans turned off and everything started working again. I only had messenger open in the background. These were other programs with far more computing power - Google Chrome, MS word, iBooks, etc. Facebook Messenger was the top CPU process - 60% or something - with others nowhere close to that number. I did a little research online, which advised to check the Activity Monitor. While I am pretty tech savvy in using the computer, I am not strong in the underlying workings of software and hardware.

Nothing helped, and I was feeling like a I might have a serious problem. I checked the wifi, closed and reloaded tabs, did updates, etc. My brand new PC with 8GB of RAM was running the fan like crazy and couldn't even keep websites loaded. This app is just fine on mobile platforms.
