Wolfn Posted January 27, 2022 Share Posted January 27, 2022 Randomly I get white lines into my JPG export. I never know until I view the output image. See attached images. Wolfgang Quote Link to comment Share on other sites More sharing options...
Andy05 Posted January 27, 2022 Share Posted January 27, 2022 Check, if hardware acceleration in enabled in your settings. Disabling this setting might help with the issues.

RichardMH Posted January 27, 2022 Share Posted January 27, 2022 I've had export problems with OpenCl acceleration on, so try turning it off. Edit->preferences->Performance. Quote Link to comment Share on other sites More sharing options...

But perhaps it is used for certain tasks performed at export time like maybe to speed up JPEG compression or resampling if the size is changed? If on Windows it is anything like on Macs, HW acceleration provides computational acceleration by offloading certain computationally intensive tasks from the CPU to the GPU.

As described in Tech Specs, I'd say it's not the same on Win. For both systems (ie if the description is not incomplete, and as in the case of help it is designed only from the point of view of MacOS), these properties should apply: But maybe is OP on a Mac, so hw acceleration is also involved in other things - so it's better to turn it off immediately.

I can confirm we've seen this export issue on Windows with Hardware Acceleration enabled - it usually indicates that the GPU driver is out of date. Disabling Hardware Acceleration, or updating the GPU drivers (sometimes both are required, deepening on the currently installed driver) should resolve this issue Pšenda and R C-R 2 Quote Link to comment Share on other sites More sharing options...

So it is at least somewhat like with Macs, in that some computations done at export time may be handed off to the GPU?

Wolfn Posted January 29, 2022 Author Share Posted January 29, 2022 Richards answer seems to work. I disabled 'OpenCl acceleration' under: Edit->preferences->Performance. Thanks to all Wolfgang Dan C 1 Quote Link to comment Share on other sites More sharing options...

That is how I understand it, with OpenCL/Metal acceleration active, yes R C-R 1 Quote Link to comment Share on other sites More sharing options...
