image suddenly becomes pixelated while editing masks in LRC

Question

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.

AMD Ryzen 7900X. 128GB RAM of DDR5. Nvidia 5090 with 32GB of GDDR7. Lightroom Classic 15.0.1 Release Camera Raw 18.0. Nvidia Studio Driver version 591.44

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:
