Problem with using stylus and tablet for whiteboard




I've been using Zoom for a while for teaching and often write things on the whiteboard with my stylus and tablet. I have a Wacom tablet and stylus. Until recently, everything has gone fine. However, for some reason, now when I write things using the stylus and tablet some of the strokes are recorded and some are not. Sometimes strokes will trigger a ripple around the cursor but the stroke won't be recorded. In other apps, I don't have this problem, only with Zoom. And as I said, this only became a problem recently. It has become so annoying that I have to screen share and use a whiteboard somewhere else. I did a search on Google but couldn't find how to fix it.


Any help would be most appreciated.


Thank you.



It appears I'm not alone with this problem. The fault apparently lies with a recent Zoom update. It is mentioned here. I don't suppose anyone has any ideas on how to fix this?

Pen/stylus while annotating on any shared document or whiteboard
‎2022-06-06 10:21 PM

Wondering if anyone can help with this nagging problem when annotating or writing on a whiteboard in Zoom....!

Problem: Annotating, writing or drawing with any stylus on any Whiteboard or on any shared document begins normally but after about 5 minutes the stylus begins to fail, or after about one-half page of writing or annotation. Then the character images of my pen/stylus begin to flicker and skip on my touchscreen, until the pen is soon rendered unable to write at all.

What I have tried:
I have tried two different pens--same problems.
I have tried at least two different Whiteboard apps--Microsoft Whiteboard, and then changed to the native Zoom whiteboard. Same problem. (Although, the problem at first seemed to be solved by using the native Zoom whiteboard, but eventually the same pen flicker ad problem began again to occur with the native Zoom Whiteboard!)

I have tried to clear the cache and cookies in the browser.
I have tried two different computers--the problem appeared to be solved at first when I switched to second computer--pen works find for a time, but it was only temporary 😞 Eventually, the second computer reverts to the same pen flickering and skipping until unusable.
I re-installed pen drivers (two pens are MS Surface pen and a Bamboo pen).

I have checked my download/upload speeds, which are fast (210 Mbs download, 11 Mbs upload).

What is looks like the problem may be: Not sure, but this problem feels like a "denial of service" type of issue, where the computer seems to reach some capacity limit on the amount of dynamic annotation/writing I am able to share over any app. However, there is NO problem with sharing documents of any size, it is only when I am using stylus annotation or drawing when some sort of "max out" on the amount of writing I can do occurs...

The only tech change I can identify is that I upgraded to Windows 11 at the start of spring 2022 semester. However, I did pair the pens with each computer again. This problem was never an issue for over 18 months of perfect Zoom classes using the pen/stylus on MS Whiteboard--never. Now, stylus inoperable in every class.
Maybe some deeper system incompatibilities within Zoom are causing this?

I'm running Windows with a Wacom and the same thing happened to me in the past month or so. I don't know if it's related to a Zoom update or a Windows update or both, but I ruled out a Wacom driver update being the issue because Wacom was last updated in March. In any case, I found that disabling Windows Ink for my Wacom when using Zoom fixed the issue.

in my case if i write fast the strokes will not appear, but if I write slowly it will appear. not sure what is the reason. If I write fast the subsequent strokes after the first will not appear. The cursor on my screen moves, but zoom doesn't show the writing. I'm using huion hs64.

Happens to me too! Frustrating enough for me to seek a solution online and found this forum. This has only been happening recently (since June/July). Never had this issue with Zoom before. Very frustrating. It only happens when I am the presenter and annotating my screen. I use a Wacom Intuos Pro. This doesn't seem to happen when I annotate someone else's shared screen. The issue (I think) is that after each annotation stroke, the pen temporarily switches back to "mouse" mode and therefore won't record the next stroke. I have to lift the pen and start the stroke again. The only workaround is to pause a second or so between strokes, or annotate in one long continuous stroke. Neither are good workarounds.

Here are the links to the older version of zoom I got after I created a zoom support ticket. After installing the older version of zoom (5.10.4), the pen works fine now. Apparently this is a known issue and will be fixed when the next version of zoom comes out Aug 22.


EXE 64-bit:


Being forced to update and the problem with the pen not working under annotation tool strike again. 

Then my usual virtual virtual background disappeared . Left only the blurred or none?

As of October 10, 2022, still a problem. I have a tutoring client unable to write successfully on the Shared Whiteboard with his new pen and tablet. Not only frustrating, very bad for business. Zoom - plse fix this immediately!

I have the same problem! My students can't see where I am at with my wacom intuos pen. So annoying, I will try google meet now...



I have the same problem. Whiteboard seems unable to catch up with my Wacom Intous pen. Pen works fine with One Note or Paint. For the time being I have decided to skip using Whiteboard.


Basically I hv to revert to old version every time zoom update. 
that solved the problem of Wacom pen not working . But this is still frustrating and a waste of time

Hi @RobertB123 @vananthan 

Sorry for late response

Zoom support 2 types of whiteboard. One is web whiteboard, the other is classic whiteboard. I want to check which one you are using.  


Web whiteboard example : 



Classic whiteboard example 



And as I know, both types of whiteboard have made great improments in the past year. When I try stylus on both whiteboard.  I can't reproduce this issue anymore. Hope you can take a try. Looking forward to your response. Respect🫡


Hello. The problem for me exists in the Classic Whiteboard, not the web white board.
