Local Adjustment Brush Disappears

I have LR2.2 running on XP-SP3 on HP Pavilion PC. The Local Adjustment Brush (LAB)circle on screen will often partially to completely disappear as I enlarge the brush. It starts out OK (concentric circles) then as I make it larger it looks like only the upper left one-quarter of the brush is visible and will completely disappear if I make it too large. The only remedy seems to be to quit LR and restart the computer. It usually works then but the next time I start LR I have the same problem.
Anyone know if this is a bug or do I need to do something in the settings...
Thanks,
Don

Re: Local Adjustment Brush Disappears
I see the same problem, and it only happens when PhotoshopCS4 is open concurrently with LR2.2. I see this behavior on two different machines (notebook and desktop, running WinXP Pro SP2). LR2.2 and PS CS4, patched up to date, were freshly installed on both machines.

Re: Local Adjustment Brush Disappears
This happens to me whether I have CS4 open or not. The only way to get the full circle of the brush back is to quit all programs and restart the computer. Sometimes even this doesn't work. I downloaded LR 2.3RC and it's still a problem. Posted this on Lightroom Journal and on Lightroom Killer Tips and I got no answer from LJ and a not so helpful one from LRKT. Guess we're the only ones so Adobe need not put any resources on our problem.
Bummer.............

Re: Local Adjustment Brush Disappears
I seem to have made some progress by reading the following post:

http://www.adobeforums.com/webx/.59b604fb/0

Tweaking the hardware acceleration setting, to turn it off, fixed the problem. I then turned it back on, and the problem is still gone. So it maybe that some confusion in the Windows registry was causing this behavior.

Re: Local Adjustment Brush Disappears
I tried decreasing the hardware acceleration one notch to 'Disable cursor and bitmap acceleration' and the brush is OK. If I take it back to full, the partial brush is back.

So, guess I'll leave it at the partially un-accelerated state; although it seems that this should not be necessary.

I'll keep checking this once in a while to see if there are further developments.

Thanks

Re: Local Adjustment Brush Disappears
Upgrading the Nvidia video driver to the latest available rev corrected this problem on my desktop machine. I should mention that both the notebook and the desktop machines have Nvidia graphics chipsets, and where experiencing this very problem until the work I did today to address it.

Re: Local Adjustment Brush Disappears

PROBLEM SOLVED!

 

Press "H" to unhid the pins.  I had the same problem and did all the things suggested here like updating drivers and turning down hardware acceleration, but none of those worked for me.  Then I saw in another forum the "H" was the hotkey to hide/unhide the local adjustment brush pins.

Re: Local Adjustment Brush Disappears

I don't know if this post is still monitered but I'm having the exact same problem with Photoshop CS4 Extended, (dissappearing brush). It seems to come and go. Also I tried the "H" key and all that got me was the hand tool. So if anyone has any more input I would welcome more suggestions. I took a screenshot of an image that demonstrates the issue and attempted to attach it to this post.

Re: Local Adjustment Brush Disappears

this post is actually about Lightroom, not Photoshop.

However, I think I've had the same issue with photoshop that you've been describing, where I couldn't see the bounds of the size of the brush anymore and i was guessing as I kept working.  Usually it comes back after I restart photoshop or my computer.

maybe it's a memory thing?
