Description

Provide a detailed description of the issue

In Lightroom CC, in Develop Module, moving the adjustment

sliders or just moving the cursor anywhere often causes the picture I'm working on to mostly turn bright white, or mostly bright white with holes. Moving cursor on or off the adjustment panel restores picture (see attached examples). Only happens when program told to use Graphics Processor via Edit>Preferences>Performance--does not happen when this box is not checked.

Please place an X to the right of the option showing how often

you see this issue using specific steps. (Ex: 'Every few times a game is started it flickers.' <- This would be "Often")</span>

Hi turnsalot,

I reviewed the video and pictures; the issue is related to the rendering process, the application requires many resources from the system. I suggest you to try installing manually the latest graphics generic driver v. 4444 from our website. Intel® HD Graphics 520 v.4444https://downloadcenter.intel.com/download/25957/Intel-Beta-Graphics-Driver-for-Windows-10-and-Windows-7-8-1-15-40-?product=88355 https://downloadcenter.intel.com/download/25957/Intel-Beta-Graphics-Driver-for-Windows-10-and-Windows-7-8-1-15-40-?product=88355 Steps to follow:1-Download the zip file of the driver from downloadcenter, unzip and keep file in the desktop.2-Turn Internet connection off3-Go to device manager>Display Adapter, right click Intel HD graphics and select uninstall driver (check delete box)4-Restart the computer5-Go to device manager>Display Adapter, right click over Microsoft generic driver select Update driver, browse search for graphics folder at desktop (step 1)6-Restart system and review graphics driver version installed from device manager or Graphics control Panel.

Hi Mike C:

Thanks for getting back to me. I changed the driver as you suggested, and it installed successfully.

Unfortunately, the problem persists.

My question is, based on the data I sent you, if you could tell whether this is a Lightroom problem, or whether there is something wrong with the hardware. I just want to make sure that I do not have a defective unit so I can exchange it if needed during the 30-day period.

While I ran the Lenovo GPU tests that came with the system, are there any other independent tests that you can recommend I run to ensure that I do not have a faulty unit?

Thanks again for your help.

Hi turnsalot,

It is possible to review the processor health using our stress test called Intel® Processor Diagnostic Tool. https://downloadcenter.intel.com/download/19792/Intel-Processor-Diagnostic-Tool https://downloadcenter.intel.com/download/19792/Intel-Processor-Diagnostic-Tool Regards,Mike C

Thanks, Mike. I ran the tests, and the system passed all the tests, so I guess that it works fine. I just won't use the GPU.

Thanks for your help.

Hi turnsalot,

I am glad your processor is working properly. Video and photo editing applications require more system resources than the rest of the applications and there is a delay while displaying the changes. Mike C
