Screen goes black using brush tool in Lightroom Classic!!@

[rmunk43]

1. OI’m still having issues with Lightroom Classic, 8.4.1 release, when using the brush tool – constantly the screen is going black back and forth!!  This is getting to be a pain in the ass – the New Lightroom made big deal about the new use of graphics cards, well for me it’s not working.

Below is my system:

Hi there,

We apologize for the issue you are facing with Lightroom Classic while using the brush.

Would you mind going to the Preferences for Lightroom Classic > Performance > select OFF from the drop down under Use Graphics Processor and then relaunch Lightroom Classic to check if it helps with the screen going blank?

If this works then I would recommend you to update the drivers for your Graphics card from the manufacturers website as old/obsolete drivers may cause this issue. You can also check the below mentioned link.
