Aongus Collins Posted March 31, 2021 Share Posted March 31, 2021 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.

Staff Gabe Posted April 1, 2021 Staff Share Posted April 1, 2021 Hi @Aongus Collins, What GPU have you got? What is your driver version? Quote Link to comment Share on other sites More sharing options...
Aongus Collins Posted April 1, 2021 Author Share Posted April 1, 2021 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.

Staff Gabe Posted April 1, 2021 Staff Share Posted April 1, 2021 Ah, intel 630. I think we saw this in the past. Can you check on intel's page too and see if there's an update? I have Asus laptop that never seems to detect when there's a new Intel HD driver. Quote Link to comment Share on other sites More sharing options...
Aongus Collins Posted April 1, 2021 Author Share Posted April 1, 2021 @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. Quote Link to comment Share on other sites More sharing options...
Komatös Posted April 2, 2021 Share Posted April 2, 2021 There is a new driver for your graphics card. https://www.nvidia.de/Download/driverResults.aspx/171826/de Quote AMD Ryzen 7 5700X | INTEL Arc A770 LE 16 GB | 32 GB DDR4 3200MHz | Windows 11 Pro 23H2 (22631.3296) AMD A10-9600P | dGPU R7 M340 (2 GB) | 8 GB DDR4 2133 MHz | Windows 10 Home 22H2 (1945.3803) Affinity Suite V 2.4 & Beta 2.(latest) Better translations with: https://www.deepl.com/translator Interested in a robust (selfhosted) PDF Solution?

Aongus Collins Posted April 2, 2021 Author Share Posted April 2, 2021 @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. Quote Link to comment Share on other sites More sharing options...
Komatös Posted April 2, 2021 Share Posted April 2, 2021 Maybe it's the Intel graphics driver. You could try downloading the latest driver from Intel. Then use the Display Driver Uninstaller to remove the Intel driver and install the downloaded driver. https://downloadcenter.intel.com/en/product/98909 https://www.wagnardsoft.com Quote AMD Ryzen 7 5700X | INTEL Arc A770 LE 16 GB | 32 GB DDR4 3200MHz | Windows 11 Pro 23H2 (22631.3296) AMD A10-9600P | dGPU R7 M340 (2 GB) | 8 GB DDR4 2133 MHz | Windows 10 Home 22H2 (1945.3803) Affinity Suite V 2.4 & Beta 2.(latest) Better translations with: https://www.deepl.com/translator Interested in a robust (selfhosted) PDF Solution?

Aongus Collins Posted April 2, 2021 Author Share Posted April 2, 2021 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. Quote Link to comment Share on other sites More sharing options...
Aongus Collins Posted April 2, 2021 Author Share Posted April 2, 2021 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.

Komatös Posted April 2, 2021 Share Posted April 2, 2021 Why on earth did you use the assistant installer and not the direkt download? I rhink the igfx_win10_100.9316,exe is for you. https://downloadmirror.intel.com/30266/a08/igfx_win10_100.9316.exe Quote AMD Ryzen 7 5700X | INTEL Arc A770 LE 16 GB | 32 GB DDR4 3200MHz | Windows 11 Pro 23H2 (22631.3296) AMD A10-9600P | dGPU R7 M340 (2 GB) | 8 GB DDR4 2133 MHz | Windows 10 Home 22H2 (1945.3803) Affinity Suite V 2.4 & Beta 2.(latest) Better translations with: https://www.deepl.com/translator Interested in a robust (selfhosted) PDF Solution?

Aongus Collins Posted April 2, 2021 Author Share Posted April 2, 2021 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 drivers.
