Local adjustment brush blinks Viewer window
I haven't used C1 for maybe some 10 days. And I have automatic updates on Windows 8.1 set to "on", so maybe something updated during the time I was using the machine for other things.
When I go to brush an area on an .arw (Sony RAW) file, the moment I click on the file in the Viewer window, the screen momentarily goes grey, and but then shows the image again. Dragging the brush cursor (as in "to select an area to adjust") the screen goes grey again. I also notice the "busy workng" star appears as long as the Viewer is grey.
So I conclude that for some reason, C1 is demanding an unreasonable amount of computing power. Or the computer is suddenly supplying a lot less. Before, the computer gave me plenty of power so I could make selections in real time. I cannot imagine what changed.
I have 32 GB of RAM on this home built machine and am using a GeForce GTX 760 card. Using Task Manager, I see that C1 is only using 8 GB of RAM and nothing else is using very much (I estimate in total another 1 GB of RAM in use). I have an Intel i7-4770 cpu with 8 cores, 3.40 GHz. Task manager shows me that while selecting, core utilization goes from some 2% to 88+% on all 8 cores. Is there some way in which the Nvidia card "suddenly" isn't doing any work??!! 🤓
Can anyone suggest where to start to determine why this is suddenly happening? In the past, the machine always gave me plenty of power to run C1 w/o any hiccups.
Running C1 8.2.0.124 64 bit.

FWIW, I opened GIMP and made some large adjustments on a file, but I really do not know how to simulate a load in GIMP like C1 might cause, so while the computer was not fazed by my "test", it also was not a very well-founded test. Anyone have suggestion how I made stress-test the computer. That is, narrow the fault to either a C1 setting or to some problem in the computer? 0 -
As a quick test try setting OpenCL usage to "Never" in the Preferences and see what happens.
Best to restart C1 afterwards.
I have no idea if will change anything but it is a quick and simple test and the sort of problem you describe might be GPU related.
If that makes a difference maybe check for NVIDIA updates or Windows drivers recently applied to see if there is anything that might relate and then take things from there.
HTH.

I would also update CO8 before you try anything else. 0 -
Wasn't there recently an issue with a C1 version and a NVIDIA driver update. Ironed out already by updated updates 😊 0 -
Thanks to all for your replies.
Due to the "magic" of computers, after a complete shutdown (and my sleeping on it overnight), C1 and my computer are functioning normally again: local adjust selection works perfectly and in real time. No more blinking. I have no explanation. 🤭 Unless some component is beginning to fail....?
@Paul_S I wasn't aware that the 8.3 update did much more than improve tethering. Hence, I have not upgraded. Going to version history of C1, I see there are "over 30 bug fixes", so I guess I will take the chance. Here's hoping I actually gain something, and that in my installation overall isn't damaged!? 🙄0 -
There seems to be a few odd things happening with my WIn 7 installation recently, not the least being some very erratic Firefox events, Explorer failing (kill and re-start works without a reboot but re-boot always advised as soon as viable).
After a recent Win update the gadgets stopped working on re-boot and I could not get them to start up. Suddenly, about 5 re-boots over some weeks, they started to work again.
C1 has a few situations where it crashes after excessive numbers of non-responding keystrokes but the non-response seems to be caused by non-C1 activities.
These problems are not very predictable nor are they consistent and repeatable. I can;t see any log of problems for hardware issues that relate. I have 2 SSDs and have run diagnostics on them - they seem OK. They are quite full at the moment. I have no idea if that might be a problem somehow.
Often a reboot will solve problems. Always worth a try if nothing else does. There are some very complex relationships going on within modern computer application developments.
