Lightroom Classic 15.2 graphics memory leak

LightRoom Classic 15.2 build: 202602111402-ec4112e8

Only this release has a fast memory leak in the graphics card memory (Nvidia GeForce RTX 4060 Ti 16GB).  It  uses up almost all the memory just exporting 8 files to Tif to be edited in PTGUI Pro that also uses graphics memory and crashes repeatedly until exiting LRC, and that fixes the problem.

However it is not efficient to have to close LR every time I export files to either Photoshop or PTgui Pro.

Lightroom Classic 15.2
build: 202602111402-ec4112e8

MS Win 11 Pro
v: 10.0.26200 Build 26200
x-64 based PC
ASUS motherboard Proart z790-creator wifi
96GB memory

Graphics: Nvidia GeForce RTX 4060 Ti 16GB

C: drive has 495 GB free.

Lightroom database and photo collection on 2 other drives has always run smoothly.

Kind regards from Hans

    @hans christian LRCC user , ​@Fremen9  As mentioned several tims here provide a copy of your 'System Info'. This can be get from the Lightroom menu item Help > System Info.

    Without these information all proposed solutions are a look into the crystal ball.

    I have the same video card, the 4060 with 16gb and I noticed lightroom classic is using way too much RAM and killing my system.  I have to close lightroom classic when my entire computer slows down because all the RAM is used. 
    I checked the version of lightroom classic and its 15.2 
    I’m going to try downgrading to 15.1 to see if the problem goes away.

    Please do the LR menu command Help > System Info and copy/paste the entire contents here so we can see exactly which versions of hardware and software LR thinks you're running and important LR options that are set.

    Is your system up-to-date? Do you have installed all recent updates and patches for the operating system and the device drivers, especially the graphic driver.

    Please make also sure that you have installed the Studio version and not the Game Ready version of your NVidia driver.

     

    Provide also a copy of your 'System Info'. This can be get from the Lightroom menu item Help > System Info.
