OpenCL problem in 1.9.0.733

[walt.farrell]

I tried creating a new document from the clipboard (which contains a screenshot).

Without OpenCL enabled in the Photo Preferences I get this, as expected:

 

With OpenCL enabled I get this:

@walt.farrell are you on the latest drivers for your cards?

[walt.farrell]

Note: I get inconsistent results. I closed Photo, restarted it, used File > New from Clipboard again. A couple of times I got the result I showed above. Another time I got the proper image in the workspace, but the black preview in the Layers panel. And then (10-15 seconds later) the Layers panel updated to show the proper image in the layer thumbnail.

Good question, Mark. I will check.

OK - the "new from clipboard" part is probably the interesting bit here. I assume you can load a document normally etc? What happens when you create a new document, then paste into it?

[walt.farrell]

Yes, I can load JPG and PNG files normally (and with impressive speed).

I then tried a RAW file. It loaded properly into the Develop Persona, but when I Developed it the final image had a black square over part of the image which was not there in the Develop Persona, nor while the Developing progress bar was active, and is not in the original image:

I closed that image, and reopened the RAW image, and repeated the Development process. Again I got a black square over part of the image, but a different part:

(I can make that RAW file available via Serif's Dropbox, if needed.)

Pasting into a new document: I created a new document (Letter Preset) and got the expected white canvas except for an artifact in the lower left:

Zooming in/out removed that artifact.

I then pasted my screenshot into the document and that worked properly.

I have not yet checked to make sure my drivers are all up-to-date, but I thought I would try switching from the NVIDIA GeForce GT 630M to the Intel HD Graphics 4000 just to see what might happen.

I have the same issue with New from Clipboard.

When creating a new document, I got something different: The document had a gray background in the workspace rather than the expected white, but it was white in the Navigator panel:

Zooming in/out did not change the document in the workspace, so it seems not to simply be a momentary rendering issue.

Yes, I'm on the latest ones I can find for my graphics cards and CPU.

 

[walt.farrell]

Also, I've found that with OpenCL enabled I cannot use Ctrl+N more than once. I can create one document (Letter preset) but when I try to create a second one Photo beta goes into "Not Responding" state, with Task Manager showing high CPU utilization (15-20% or so) and also showing "GPU-0 Copy".

I also cannot Open two images (JPG or PNG). The first one opens; and I get "1 Document loading" for the second one, and Photo Beta goes into "Not Responding", and roughly the same CPU utilization.

I have a Windows .DMP file for one of these, but it's big enough that I may need a Dropbox link to upload it.

[walt.farrell]

I did some testing on .734 today, @Mark Ingram. I have now tried on several occasions to Open more than one file (JPG or PNG). The first file opens. The second Open does not complete. I created another .DMP file using .734, in case you want it.

More testing...

1. I disabled the NVIDIA GeForce GT 630M display adapter from Windows Device Manager. Renderer was still the default Intel HD Graphics 4000 adapter. Then I could successfully load multiple images into Photo.
2. I then re-enabled the NVIDIA adapter, and disabled the Intel HD Graphics 4000 display adapter. This caused some screen oddness as apparently it was what Windows was using for screen display, and I noticed that in Photo the Renderer was listed as Microsoft Basic Renderer. However, again, I could successfully load multiple images into Photo.
3. I then re-enabled the Intel HD Graphics 4000 adapter, and everything still seems to be working. With both adapters active, and the Intel adapter for the Renderer, I can still load multiple images.

This leaves me puzzled about what was going on, but the immediate problem seems to have been resolved somehow.

I too have probs with HW Acc. = ON. I think it's the display driver as differrent zoom-settings give also different results.

(GT 750M)

with HW Acc. = OFF everything is fine

Img = HW Acc. = ON / painting with a pixelbrush

I'm getting the same blockiness as Walt with OpenCL activated. I also find that if I zoom in and out, AP will crash.

[emmrecs01]

Just tested this on my system (details in my signature), having activated the CL option and had APh Beta restart: opening a .jpg, no problem; opening a .CR2 RAW, initially I see a "black rectangle" upper right corned of the image, but it disappears within two or three seconds; pressing "Develop" (no changes made from default settings) the phenomenon repeats, i.e, initially the developed image also has the black rectangle in the same upper right corner but it similarly disappears within two or three seconds.

So, a graphics redraw problem?

Perhaps, but for me the block did not go away, even with zooming in and out.

For those of you who are getting the rendering issues, are you able to start and complete the benchmark?

No. It hangs before reporting the Raster (Multi CPU) results.

[emmrecs01]

@Chris B

Benchmark completes for me.  Screenshot below, system spec in my signature.

I assume the fact that my earlier attempts to run Benchmark failed because I had not then activated the CL option?  Previously, several results were showing as N/A.

Jeff

[Chris B]

Thanks. I didn't want to spend ages testing this if, everyone affected by the artifacts couldn't finish the benchmark. They're seemingly unrelated then, I guess. 

 

[walt.farrell]

I've now installed 1.9.0.767. It has enabled me to finish the benchmark with OpenCL enabled on my laptop Windows 10 PC.

However, with OpenCL enabled, I am still unable to use Photo at all.

If I open a file, or create a new file via New from Clipboard, I get a gray background layer in the workspace. The Navigator has the correct image, and the layer thumbnail is correct.

[Chris B]

I have absolutely no idea what's going on there Walt...

I reproduced some graphical issues with an uncompressed raw but I think that was thhe render tiles being slow to update.

[GeoffH]

I have just tried to replicate the problems outlined above with 1.9.0.767 on my vintage PC with a AMD Radeon 6800 based card and I failed.

With Open CL enabled I managed to open new from clipboard twice and 7 new documents using the Ctrl N. I managed to stop the program eventually when I tried to open the 3rd RW2 file concurrently but until that point no blocks and pan and zoom worked fine. No issue either with developing raw files.

Just my 2 cents worth.

I have exactly the same problem. After the release of 1.9.0.767 everything worked as expected. The following day it appeared to be just like Walt described. Open CL not usable at all with the same screen Walt showed. My computer is an older i5 with 8Gb RAM and Geforce GT730.

Hope something can be done.

Thanks, Peter

@Chris B: I have tried this again with 1.9.0.780, with the OpenCL performance option enabled, and the behavior is different. On the positive side, I do not seem to get the gray-filled screen rendering any more, and I am able to Open a file successfully.

However, when I try to open a second file, Photo starts using very high CPU (75-85% of 4 cores) for awhile, then settles down to using 35-45% of 4 cores consistently after that, but never finishes loading the second file.

I have tried this several times, and have had to use the Task Manager to kill Photo each time. Also, once it stayed at the 75-85% of CPU usage (based on the fan noise) and Windows was completely frozen. I could not get the trackpad to move mouse pointer, or the taskbar to become visible, and even Ctrl+Alt+Delete would not bring up a menu. I had to physically power-off, and then restart Windows.

Also, my benchmark performance, which has not been good (GPU worse than CPU for the Raster measurements) is now worse

[PetervL]

The 1.9.0.780 release fixed the problems I was experiencing. They very much resembled the problems Walt was describing. I hope that Walt's problems will soon come to an end as well.

I do want to thank the Serif team for all they have done, Congratulations!
