LR smart features over allocate VRAM, causing frequently freeze

[jim_3092]

I'm experiencing a increasingly frustrating problem with Lightroom. Whenever I use "smart" features such as noise reduction, masking or spot removal, lightroom start to consume a lot of VRAM. I have 64GB DDR5 RAM, Intel i7-14700k, and an RTX 3080 with 10 GB of VRAM and LR easily eats that in a few minutes of use. The VRAM consumption seemt to reduce after a while, however, the RAM usage then increase, around ~25GB, suggesting that the VRAM is dumped to RAM instead. Doing so causes distinct and frequent freezes, making LR impossible to work with without restarting it ever 10 minutes. The only solution seems to be to restart it. I have tried to disable the GPU acceleration entierly (both in LR and PS) but distpite this, LR still allocate VRAM and cause frequent freezes. Have anyone else shared this experience? Is this a known issue? Are there a fix to this, or am I stuck with a broken LR?
