    Moved from 2020.3.48 to 2022.3.9 recently and I started getting system alerts about running out of memory due to Unity. After a quick profiler check, it seems like "_CameraDepthAttachment" Render Textures are endlessly created and never disposed. I got the attached profiler results in an empty scene, using the Default editor layout. Just submitted bug report IN-54652 (Issue Tracker website does not respond at the moment so I don't have the link for that).

    Hello and thank you for the bug report. Have you tried other 2022 versions, e.g. 2022.2.15f1 or earlier (Note that their size might be faultily reported there, so their count and the system monitor values would be more relevant)? I have an odd-ball suspicion, based on this being the second temp RT leak report I'm seeing on the forums today.

    No sorry, I've jumped straight to 2022.3.9 from 2020.3.48.
    I see there is already a 2022.3.10 version with a similar fix but it looks related to UIElements, which I'm not using. In any case yeah I too think the size might be miscalculated because my system only has 32GB of memory (and I don't have all that free space on disk for virtual memory).

    Hi, this huge RenderTexture memory leak was introduced with 2022.3.8f1 version and exists also on PC. It's strange and unacceptable, that this kind of bugs sneak into LTS versions.

    Fair, it should not creep into LTS, but there is a balancing sweet-spot to be hit between the speed of fixes and backports vs completeness of guarding against all possible scenarios. The root cause for this regression has been analyzed, resulted in extra tests, and the data from that and other analyses will be used to optimize that balance and the general process.

    Hope the fix arrives soon anyways. The editor hits memory limit very quickly and closing and reopening Unity dozen of times a day wasn't really on my workflow until now.

    Any info, was it fixed in 2022.3.10, we had to rollback to .7, as we hit out-of-memory like in 30 seconds :rolleyes:

    I’ve started using 2022.3.10 as soon as the update landed and the specific problem I reported was definitely fixed, memory is stable. Maybe you encountered a different one? Can you check the Editor memory usage?

    Ok, installed 2022.3.10 and I can confirm that this issue has been fixed.

    2022.3.10 , Windows, _CameraDepthAttachment_2205x1149_Depth t:RenderTexture created every frame. From Memory profiler. Is it really fixed?

    Memory Leak is back as soon as I switch to Android.
    It happens when I use "Always Refresh" and Alt-Tab to another app, Chrome or Photoshop for example, while Unity stay active in background.

    oh dmn, can you please file a bug report about that via the Editor menu 
    Help > Report a Bug
    and post the issue ID here (once you get an email reply from us) to make sure that we can look at and fix this in a (hopefully) speedy manner?

    (Also, I fully expect that to be a separate issue that might have coexisted and just not been seen when fixing the other leaks as its likely happening somewhere slightly different)
