Lightroom 6-Adjustment Brush- round to oval? and too many cursor points

[davide70602713]

Hello,

I'm having problems with my adjustment brush that is intermittent... It seems that when I enlarge the brush it starts off round from size 1-8, then if I enlarge it from size 9-28 it turns into an oval with only the top half visible, and then when I enlarge it from sized 29 up it returns to the round shape with the whole circle is once again visible... any ideas what causes that and how to fix it. it's an intermittent problem so sometimes it happens and sometimes it doesn't. The other strange thing is when i use the scroll on my mouse to reduce the size of the brush the cursor turns into 2 brushes and then as I decrease more it turns into 4 brushes... when I move the cursor out of the photo to the controls, it still has 4 points on the cursor..... Any ideas why that is happening and how to get rid of the oval for intermediate brush sizes and get rid of the 4 cursor points without shutting down Lightroom and re-opening?

Please give your system specs and the exact version of LR you are using.

I just tested this and don't have any of that behavior.

Lightroom 6.0
Windows 7 64-bit operating system.. Service Pack 1 Intel 3.0GHz and 4 GB Ram..

You might be running out of RAM. Just a guess.

4GBs of RAM was the minimum for running Win 7 (I have 16GBs on my Win 7 PC).

Make sure all other program are shut down while using LR.

I shut down most of my programs and still had 50% of my RAM still available.... same problem

Try going to the Preferences dialogue and in the Performance tab, turning off the choice to use the Graphics Processor.

If that doesn't work, try resetting your preferences:

Resetting the lightroom preferences file - updated

I turned off the choice to use graphics processor.. no change and then re-set the preferences and again no change...

Here's more info... If I change the brush size with my mouse, sometimes the oval is from size 4-21 and somethings from 7-30... but when I scroll up to the point that it becomes a circle then scroll down, at size 15 it becomes a double cursor and at size 7 it becomes 4 horizonatlly parallel cursors. The 4 cursors remain in Lightroom but if I go to another it returns to a single cursor point and I can go back into Lightroom and I only have the 1 cursor point... the cursor point to the far right is the one that works, the three to the right of it just sort of follow it around but they don't do anything if I put on of them on the point that I want to click.

It also sounds like you might have a graphics card problem.

When was the last time you blew the dust out of your system?

[davide70602713]

Had some work down on the computer four months ago and we cleaned out the dust... the problem is so local... just the one tool in the one program which leads me to think it's something directly attributable to Lightroom.... All other tools are working fine in the program...
