It worked for me by closing razer synapse

THANK YOU! Such a simple fix - embarrassed that I did not think to try it sooner. For those who are having trouble, mine was not titled "Message" it was the "Amazon Assistant" that was the culprit. Good luck!

theres a huge white box in the bottom right corner of my screen and tis so annoying, u cant even restart to get it removeD

CTRL is control, not central. Just so others are not confused. I will give this a try. Thanks.

It doesn't appear in the task manager. What do I do? (Windows 10).

thanks!

A faster way to get to task manager is Ctrl+Shift+Esc.

YES. thank you so much. This stupid box has been on my computer for days lol.

i had the same issue. In my case the white rectangle image was in the right bottom corner just above task bar. I opened the task manager and killed the fdm process. You may check for any application which you have installed in that list and kill it one by one. Hope it helps

Thank you so much!! its been there for a week and its so annoying and i just got rid of it. Thanks again!

For me at was caused by a program i am using, called "screen shot captor", disappears when i close it. it comes every now & then, donno why.

it's not on the list of task manager

thank you so much

i didnt understand or its the wrong thing there are white boxes on my right screen just bouncing like they are spinning or something i cant even click on my channel or notifications.. I think my right side of the screen has a problem :/

I have a problem, it's like a big white box at the corner of my screen, but it's invisible. I can't click anything on it, and if I right click, I can Reload, Go Back, Or Go Forward. It only lets me reload, so I clicked on it and now the invisible box is bigger. Help!
