CanNOT use LARGER brushes, they freeze on the screen

[widors5th]

Anyone familiar with this bug? When increasing brush size (not to anything extreme, just sizes like '10' or even less) then the brush will not draw on the screen, I can only move it from the panel to the border of the image, and then it's stuck. Impossible to move the pointer on top of the image at all. Very annoying.

I read people having other issues with brushes, switching off the GPU, but that didn't help a bit.

Running the latest version of everthing, LR 10.3

Somewhere in this community, another posting on similar to this exists, I remember failing to assist. Member had problem with Adjustment brush, not not with other brushes.

ahh, link: https://community.adobe.com/t5/lightroom-classic/adjustment-brush-tool-issues/m-p/12223586

But nothing was solved, The member returned to LrC a few days later and by magic LrC was behaving.

So.

Have you shut your computer down for awhile, then turn back on?

LOL, the very first and basic solution that nobody wants to hear actually worked. A full reboot of my machine fixed it for now. I'm not convinced yet it will not return, but at leat there is a workaround for now. Thanks for your suggestion.

For the record: GPU settings in LR are on Auto.
