Memory leak issue
Hi! After adding Clarity through the GTM we faced the issue with memory leak. Seems that there are a lot of strings allocated in the memory and for some reason, it can't be cleaned up. After some time of usage of our search page we can see the following:
And the context in which the retained objects are stored:
UPD:
I investigated the issue a little bit more and found the following pattern:
The memory starts leaking when the /collect endpoint not calling anymore.
When you play with a ui by firing a lot of different DOM events there is a moment of time when the /collect is not sent anymore and after that, the memory leak occurs.
Same issue. for some reason /collect calls stop and after that app memory usage just grows until Out Of Memory crash.. Can't really detect when that happens but it might be related to browser tab idling for longer time.
For now we will remove clarity integration as this is affecting customers. Will monitor this issue as /clarity was helpful for us.

I hit this issue too.
In my case it's happening on a page with an audio tag with src="data:audio/mpeg;base64,.... This base64 is about 100MB.
Seems that /collect is sending the whole content of the tag (3 times):
After that, the /collect endpoint is not called anymore.
IMG tags with src="data:..." causes memory leak. (img tag was created by dropzonejs, image on disk was 2.6MB)
I was able to fix/workaround the memory leak in my websites by adding img[src^="data:"] rule in Settings > Masking > Mask by element
https://learn.microsoft.com/en-us/clarity/setup-and-installation/clarity-masking#mask-by-element
We are experiencing the same on our webapp, and when it crashes unfortunately this can cause data loss.
I can see that excluding elements with[src^="data:"] might help, other than this are there any other updates?
Hi @ClaritySupport Are there any updates about this issue? We would really like to start using Clarity again, but this issue affects our customers so much that we had to abandon it :(
