OpenCL & v1.9.0.734

[AiDon]

Currently using a NVIDIA GTX1050/4GB with driver v456.38 and the Performance settings are this:

the previous reported issues with Panorama stitching and HDR merge are still causing immediate exit crashes and opening more than one image at a time still causes crashing if the GTX1050 is used as the renderer

If I change to use the HD Graphics as the renderer on a external monitor the immediate close issue doesn't happen, but opening 3 uncompressed ARW images (A7MIII) the second image, or 3rd image on the internal display, wont show a preview and it just looks like this:

 

In some cases there is blocking on the display  where the screen redraw doesn't seem to complete:

Hey AiDon,

The crash is likely the nvwgf2umx.dll crash. If you have a report, search for that and it will pretty much confirm it. Using OpenCL I would imagine you get the same crash.

I'm interested in those rendering blocks though. Can you attach a copy please?

No crash reports at all, when you say attach a copy of the rendering blocks, a copy of what? ... using the setup with HD 630 or the GTX1050 it happens all the time as you can see with a ARW image opened in develop here the screen redraw is very slow, I have also attached a MP4 for you. Always at least the dark block on the bottom RH side of the display appears.

Note that the only way to get the Beta to work normally is to use the v442.92 NVIDIA drivers ... but it isnt an option as turning on OpenCL the blocking appears as above, so the only option is a setup like this as opening 3 images (ARW) the third has no preview if used with OpenCL:

Also it is difficult to understand why as this is the benchmark:

Hi Chris,

Managed to get a crash dump today and the error is Unhandled exception at 0x00007FFA769150B8 (nvwgf2umx.dll) in 3d5fe9fc-0e8f-417c-9a9b-6c1d970af29b.dmp: 0xC00000FD: Stack overflow (parameters: 0x0000000000000001, 0x000000D72B999000).

Attached is the dump ...

Thanks Don,

This is the Nvidia dll crash we keep seeing. I'm adding this to my bug report—thanks.

I meant a copy of your file. I want to make sure I'm using the same uncompressed file you are to see if I can reproduce it. I have a plethora of machines at home I can try the file on, all running OpenCL.

OK here is one that I posted a shot of above with the BLOCK in the RH bottom corner but for the crash on exit just copy the image 2 times, rename the 2 new copies, and select all 3 at the same time. But really that crash happens with Compressed ARW, RAF, CR2 etc.

Is it possible you could try this with the HD graphics driver disabled in Device Manager ?

Hi AiDon,

I got the black bar to appear for a second or two with OpenCL on. Will pass this over for investigation—thanks!
