Lightroom 2024 Object Brush edges cut off

[Zak3550919346rj]

Hi everyone,

I'm running Lightroom 2024 on a 2018 Macbook Pro, iOS 13.4, with the Intel Iris Plus Graphics 655 1536MB graphics processor. 8 GB 2133 MHz LPDDR3 memory if that matters. I have "use graphics processor" selected. If i unselect it then Lightroom gets unusably slow.

In basically every photo, when trying to add an Object mask, the object brush is randomly cut off from certain edges. I can somewhat fix this by moving the picture around, and then it gets cut off from other edges. There is no pattern to the location at which the object mask stops showing up. It doesn't "select" beyond the barrier and none of my other friends have this issue. What's going on?

Lightroom has no version called 2024. 

Please go to Help>System Info… and provide us with your software's installed version number. 

Regardless, your system's GPU does not meet Adobe's minimum specification for GPU VRAM, which is 2 GB.
Please see: https://helpx.adobe.com/lightroom-cc/system-requirements.html

Moving to discussions.

Thank you! It's version 7.2. Darn. Is this also likely the reason that my "brush" nebver fully selects an object and takes multiple passes to select what I want? I guess that's graphics related too.

The image you attached looks like you may have AutoMask enabled on the brush stroke.
