image suddenly becomes pixelated while editing masks in LRC

Does anyone know what's happening?  So I'll be editing masks and suddenly the image because very pixelated and I can't adjust anymore (I'll move a slider or a curve but no changes happen to the image).  At that point, all I can do is close LRC and reopen it.  But it starts to happen again.  Sometimes it'll turn to a red background.

Such are often based on issues/incompatibilies with the graphic device or the device driver.

On a first step you should try is to switch off the GPU support from the Lightroom preferences and check if that helps to fix the issue.

Go to Lightroom > Preferences > Performance tab > Uncheck "Use Graphics Processor" > Restart Lightroom.

If it's help see here Troubleshoot GPU issues | Lightroom Classic (adobe.com) and check the different steps.

 

Another step is to try to reset the Lightroom preferences.

It's recommended to backup your preferences before you reset the preferences to the default settings:

If this doesn't help we need more informations about your environment. Please provide also a copy of your 'System Info'. This can be get from the LrC Help > System Info menu item. There's a copy button in the System Info dialog. Press this button and paste the info into your next forum post.

thank you so much for the help!  So I initially turned off the GPU use and the problem went away.  However, it became slower to edit.  So I turned GPU back on but left GPU off for previews and that still worked.  So right now, I have GPU for editing and rendering but not for previews.

Hey @Patrick22478442njpf 

Can you share what driver version your Nvidia is currently using? I remember seeing a few others having to roll back to a previous version of their Studio Driver. You can find this info in your system info. You can find it by going to Help > System Info, then copying and pasting it into a text file to attach here. This will enable us to investigate it further.
