Lightroom: Crashing with GPU acceleration on (AMD Radeon driver 17.4.4)

Glad you got it resolved.

John R Ellis: Thank you! I had searched the AMD website and found and tried various other drivers, but not that one. I have now installed it, and the Lightroom problem I reported appears to be fixed -- even with 'Use Graphics Processor' checked.

I appreciate your help!

According to these support pages, you have an older driver for FirePro V4800 (15.201.2401.0).  The latest driver is 15.201.2401.1009, released 2/15/2017:

As I described, my problem occurs when GPU acceleration is OFF.

So merging my problem into this thread is not useful. Can you un-merge the topics, or should I ask the same question again?

There appears to be a bug in the most recent AMD driver that trips up LR, and an Adobe employee indicated that a fix will appear in the next release of the driver. Meanwhile, see the official response to this topic for a workaround: https://feedback.photoshop.com/photoshop_family/topics/lightroom-crashing-with-gpu-acceleration-on?t.... If that doesn't work, try rolling back to the immediately previous version of the driver.

Lightroom 6.10 continues to crash when I make a succession of adjustments in the develop module. Lightroom versions 4 and 5 did not show this problem on this computer.

The computer has 16 GB RAM, separate SSDs for programs and Lightroom catalog, operating system is  Windows 7 64 bit. Display adapter is an ATI FirePro V4800 (FireGL V) with driver version 15.201.2401.0.

In Lightroom preferences graphics processor acceleration is disabled.

Here is a Windows error report:

I'm looking for some guidance on how to cure this problem (or at least to understand why it is happening).

This only happens on my AMD system with R9 390 with "use graphics processor" checked.  Does not happen on my Intel system.

You sure about that? Because according to their release notes for the most recent driver, they only know about the issue for the Radeon 390x series cards and there are cards outside of that affected. For example, I run an R4... so you sure you are communicating with them correctly?

The latest word is that AMD is going to push out a fix in their next driver update. 

The point for me is that NONE of the other software products I use are crashing with the AMD driver. The GPU acceleration is working fine.

While it may be that the crash happens in the driver, as Simon Chen says, it's the Adobe coding that's making it crash as opposed to the other products I have that don't.

Interestingly, when I installed the latest AMD driver the other day, and started up Capture One, it displayed a message that it was optimizing GPU performance, or something like that.

I get that it's not trivial to find this issue, being between Adobe software and AMD hardware and software. But it's there, and it needs to be addressed so that it doesn't happen again and again.
