Comments Section - Shakes and Flickers

[GraceStinson]

Each time I enter information in the Comments Section of an assignment, the screen is either shaking up and down or flickers.  This happens in both Canvas environments of the Colleges I serve.  It is very hard on the eyes and makes me dizzy.  It also becomes like a game of anticipation where I position my cursor to type additional information or attempt to delete something.  Please help.

Try restarting your computer. If that doesn't work, contact your manufacturer. By the way, what device are you using? Computer, tablet, or phone? Sharing your device details would be helpful!

Thank you for your response.

1.  I am using a Lenovo Idea Centre that has not given me any problems.  Less than one year old.

2.  This behavior is also happening on Desktop and my laptop.

The behavior can be intermittent.  I notice that when I refresh the page, it will be steady for a bit, however, it is iffy when it will behave similarly again.  It is very frustrating.

Hi @GraceStinson,

Are you able to get a short screen recording of the issue?  I was at first inclined to think the problem was specific to a device you were using, but since you mentioned it's happening on both your desktop and laptop, that somewhat rules that out.  I haven't observed this behavior myself, so seeing a video would be great to see the exact behavior and figure out some possible causes.

In addition to a possible screen recording, could you tell us what web browser you're using, or if you've tried it on multiple browsers and have the same behavior too?

Look forward to hearing back from you!

Interesting. Do you have any screen magnifyers on? If so, that might be the problem. Try turning them off.

Hi Callie-

I have included a video as evidence of the problem.  Thank you for your help.

Hi @GraceStinson,

The video was definitely helpful to see what's going on.  It appears it's scrollbars that keep showing up and disappearing that's causing the problem.  I tried this on a couple computers I have and still couldn't replicate it though, so it's probably some kind of specific combination of windows monitor settings, browser zoom, and maybe other customizations coming into play.

It looks like you're using Windows, so for at least a temporary workaround, you could try to change your windows settings to always show scrollbars. No guarantee this will fix the problem, but it's worth a shot.

Indeed, we can see in the video that she is zoomed out (small magnifying glass image on the right of the address bar).

So first thing would be to reset the zoom (can be done by just clicking that magnifying glass and then "reset")

I am also responding to Gabriel33 who stated:

If you click on Account on the left, and then Settings, at the bottom of the page, you should see Feature Options. One feature option is Disable Celebration Animations,

Please try toggling that on, and see if it stops those.

I went to both Colleges I serve and in both Colleges, this option does not exist.  The closest one I can say is the option that shows: "Emojis in Submission Comments."

Thank you!

Yes, sorry, I deleted my original reply almost immediately, after I realized that was not the issue, sorry for the confusion.
