Yes, I tried an Intel installer, but it quit with a warning (attached screengrab). I cannot risk making my system unstable. Hardware acceleration in Photo is "nice to have" but not "must have", and not worth compromising the other programs and the system I rely upon. If Photoshop has no OpenCL issues with my Intel drivers, neither should Affinity Photo. Also, there are other bugs in 1.9x, which I haven't reported due to their randomness (daily crashes and temporary freezing), so I believe the blur problem is related to these latest releases rather than my up to date official driver

Downloaded a trial version of Photoshop, which detected my graphics card. Enabled graphics processor acceleration/OpenCL, and could not reproduce this issue on multiple images, using the same drivers and hardware.

According to Intel, "A customized computer manufacturer driver is installed on your computer. The Intel Driver & Support Assistant is not able to update the driver. Installing a generic Intel driver instead of the customized computer manufacturer driver may cause technical issues..." I have installed the latest official Dell driver, dated 22/1/2021. I may install a trial version of Photoshop to see if it also has problems with my card. A guick search shows that Photoshop users have also reported OpenCL issues.

@Komatös Thank you for sharing that information. I downloaded and installed the latest driver successfully. Unfortunately it did not solve the problem. In another thread, Serif referred to "a few rendering issues with some graphics cards using OpenCL and filters", but there appears to be more to it than rendering. If you export the filtered file as a JPEG or TIFF, all is you get is a white canvas, even when the file is opened in another program. File size in this case was reduced from over 12MB to 145KB, so the content of the file was altered significantly.

@Gabe I updated all drivers, but it made no difference. Again disabling OpenCL was the only solution. However, since then I had a chance to test on another laptop, also a Dell with an Intel 630 but with a different Nvidia card, a GeForce GTX 1050, driver version:461.72. And everything worked fine. So this could be related to the M1200 Quadro, or there is a specific problem with my hardware.

Hi @Gabe I'm using a Nvidia Quadro M1200, driver version 461.09, on a Dell Precision laptop with 16GB RAM. It also has an Intel 630 integrated card. I ran the Dell SupportAssist program and it reported that drivers are up to date and there are no hardware problems.

I've been able to reproduce this in multiple images. In v1.9.2, applying a Gaussian blur with a value of 5.4px or higher will create a completely empty white layer, if OpenCL is enabled. (See video.) Switching it off resolved the issue. Blur-Video.mp4

Thanks, I'd missed that. Very useful!

Since posting my previous comment, I checked to ensure all Nvidia drivers on my system were up to date, and whether the Studio version was compatible. They were, and it wasn't. Then I launched the Nvidia Control Panel, and spotted something I hadn't noticed before: according to Nvidia, GPU selection is now managed by the Windows OS. I followed their instructions and used the Windows Graphics Settings panel to set Affinity apps to hardware acceleration (see attachment). I tested the new setting by attempting to develop a disastrously failed exposure. The idea was to stress test.

I can reproduce this exactly: lag in the GUI while developing RAW makes the the software unusable. However disabling hardware acceleration while retaining the more powerful Nvidia GPU as renderer solved the issue.

Thank you for your hard work... all the best for the holiday season, and a happy & healthy new year!

I tried but failed to reproduce this on two versions of Windows: -- Previous version, Home (10.0.18363), no hardware acceleration -- October Feature Update (2004) with hardware acceleration both enabled & disabled. Version1.9.0.834 opened .afdesign files, created in this and earlier versions of the program. Also opened PDF, tif, png & psd files without crashing. XPS 15, 32GB RAM, Nvidia 1050

I opened it without administrator, using the attached settings, and it's been working fine.

Update: I tried "Run as Administrator" and it worked fine. Also registered successfully.

1. From the Start menu, launch Affinity Designer Customer Beta. 2. Splash screen is displayed briefly, then program quits. 3. Problem persists after computer restart Windows 10 Home Version 10.0.18363, Build 18363, Dell XPS 15 9560, 32GB RAM, Nvidia GTX 1050 with latest drivers.
