P: GPU issues on macOS/MacBook Pro 15" (image turns black switching tabs)

Hey *Sympa

this morning I had the idea to re-create the ICC profile after one year. Same profile, just probably made with new algorithm by X-Rite. Now I just tried to work only one picture and I don't want to call a win, but it seems to be a little of bit better. No-one Photoshop crash. Zoom works well.

But some issue is still present, as you can see on this new video screenshot. It is perfectly visible after a minute.

You can "cheat" the video recording software by downscaling your monitor resolution. 

System Preferences -> Displays -> Scaled - "Larger Text"

I verified just now that this will reduce the monitor resolution such that when you record you are already recording at a lower resolution. 

Hope this helps. -Sympa

*Sympa I use often that app, but as I told you it isn't possible to select first the quality. Only after for exporting. My problem is that with a retina monitor, the quality recorded on screen is huge. So with Photoshop opened and recording also, my RAM and CPU can't do both things together. Do you know a way to make a video-screenshot directly in 480 or 720p?

@cloudres thank you for trying!! Apple has a builtin screen recording utility you can try using instead.

spotlight search for an app called "screenshot.app". With this you can choose to record either all or partial portion of your screen. When youre done recording hit the "stop" symbol in the to right of your menu bar. It'll open the file in quicktime.

In quicktime choose file export 720p. This'll make the file considerably smaller and easier to share. 

*Sympa I tried to do it one time with QuickTime, but as the video is recorded in retina resolutions for a couple of minutes, it requests a lot of memory. Is there a way that you know to record a video-screenshot in low resolution? I can't do this with QuickTime, because the system starts to go down few seconds after.

Alternatively I can show you it in a call with shared screen. Please let me know!

Thanks a lot for your time.

*cloudres Could you provide a screen recording after restarting photoshop, showing the exact steps / process you followed to get to the bad GPU state? The screen recording you have now shows the problem well, but not the steps to get there. This will help us to further isolate if theres a specific area of photoshop that we can triage further.

Thank you very much. Will discuss with the team.

• Are your applications installed in the default operating system directory or a custom directory. If custom, please specify the path being used?

Default directory.

• Have you turned off GPU in preferences → performance?:

I tried with the GPU on and also off. But the result is the same. I also tried to disable the change of the video card by Apple preference, but it didn't help.

• What input device are you using (mouse, trackpad, tablet) (What make and model?)

I'm using only a mouse Logitech M590. Nothing else.

• Do you have updated drivers for peripherals (Wintab, Wacom), and GPU (NVidia, AMD):

On a MacBook I can't update the driver of the video card. But the OS is to the last version, today 10.15.7 (19H2).

• Is your hardware older than 7 years old?:

No, I use MacBook Pro (15-inch, 2017) bought 2 years ago.

• Is the GPU being run in a virtualized environment?:

No.

• Is the problem is related to the OpenCL checkbox in preferences → performance → advanced being grayed out?:

The problem is present in both cases. With OpenCL on and off.

• Is there a CL device in the help → system info log?:

I don't know what you mean, but you can find my system info log on the link mentioned by @andrew_sender

• Does turning on this setting fix your issue? legacy compositing in preferences → performance:

I don't know what do you mean. 

• Did this behave correctly in a previous version of photoshop (which?):

I don't remember the exactly version, but during 2020 there were been a major update during the first semester. In that occasion the problems started.

• Is the issue reproducible on both Mac & Windows?:

I use only Mac OS.

• Reproducibility (sometimes? 100%?):

The issue occurred very often when I work on a second pictures sequentially. Or when I zoom a picture or when I switch between panels on Photoshop. The result is the same that you can see on the video-screenshot linked.

• Include file that reproduces this issue:

It happen with all NEF, DNG and PSD files that I worked. All of them have more than 10/15 megapixels. All files was developed by Adobe Camera Raw and loaded in Photoshop in 16 bit.

• Attach to bug report a screen recording of you reproducing this issue (use loom to upload screen recording):

Here it is a video-screenshot.

• Attach to bug report a screen recording of expected behavior:

I think that you can imagine how it should works 😅

• Attach to bug report the log from help → system info:

Already done. 

Hi *cloudres  Please answer the questions I supplied. Will not be able to look further until the diagnostic information requested has been filled out. 

Please let me know if you need other informations. Me and many other persons need a fix asap. This problem is going on since many months.
