Lightroom Classic 8.4: Multiple issues

I'm using LR Classic on an HP Envy x360 with Win 10 fully updated. With the 8.4 version, I am seeing random full system lockups (screen and mouse pointer freeze) requiring a hard reboot if LR is set to use the GPU at all. This does not occur with GPU set to OFF. Previous version used GPU flawlessly. Also seeing failures of the brush tool to update the display - changes, control points, and overlay mask all don't appear. This occurs even with GPU turned off. I've had to revert to the previous version of LR.

Your best first step would be to ensure that your video card driver is up to date by going to your video card manufacturer's website and downloading and installing the latest driver.  Don't rely on Windows update as those drivers are usually a couple of versions old.

Follow Lr 8.4 instructions in this FAQ https://helpx.adobe.com/lightroom-classic/kb/lightroom-gpu-faq.html to do a clean install of your GPU driver from Nvidia.

What is your Lightroom>Help>System Info... reports currently?

LR8.4 Immediately consumes all available VRAM... i wonder if that has anything to do with it?

Should have mentioned that video drivers are up to date. System is a laptop with on-processor video, I think. Radeon, not nvidia.

I am having a similar issue. I have dual GTX 1080 Ti GPUs (yes I know LR/PS only use one) with the latest Nvidia Studio Driver (version 431.70 Release Date 07/29/2019). Everything seems to work fine for a while but eventually when going into the Develop Module, the sliders move but the displayed image doesn't change. If I go back to the Library Module, the image reflects the DM slider changes but if I re-enter the DM the old, unchanged image is redisplayed. While in DM if I use the arrow keys, the film strip acts like I changed images but the main display still reflects the old image. If I exit LR, the display/mouse/etc. freeze for 10-30 seconds then everything starts working again. If I launch LR again, everything works ok for a while then the cycle repeats. FWIW, most of the time I also have PS running and routinely move back and forth between the two programs. If I open the image from LR as a smart object in PS, then double-click on it, ACR is extremely slow.

Update: It seems like the GPU freeze happens more after I do a round trip from LR -> PS -> LR after editing the photo in LR.

Unable to check the 'Use GPU for image processing (Process Version 5 or Higher)' check box; it is greyed out. I'm running on a GTX 770 which is listed as supported. Nvidia drivers are as up to date as they can be. Not sure what else I can try.

I'm running Windows 10 Pro v1903 OS Build 18362.295. And I have today's latest nvidia driver 436.02. So I don't quite get what else I can do.

Based on that have you seen Simon's recommendation earlier in the thread and attempted to reinstall your nVidia driver with a Clean Install?

I was experiencing similar issues with 8.4 and GPU support on very powerful hardware.

Win 10 (latest updates), nvidia RTX 2070, i7-6900K cpu with 64gb of RAM.

Cycling between pictures was delayed, edit tools and switching in and out of edit tools all had maddening delays, with the spinning wheel while you waited for screen to change. Edits had a lag before appearing on screen.

None of this happened prior to 8.4. I had the latest nvidia drivers, but did a re-install using the clean installation option, and seems to have helped and now seems to be working OK.

I do notice that opening LR Classic immediately grabs all 8GB of VRAM on my memory card. Closing LR Classic frees it.

I have noticed rendering lag in my browser when LR is open, and am guessing this is because LR is hogging all VRAM resources on the GPU. I can't imagine this is what was intended. Simon/Rick, Is it supposed to use 100% of GPU VRAM?
