Random square(s) at export


Recommended Posts

Hello,

I have a project with many filters, and when I try export this to JPG, then will show a square(s) at random position on JPEG on every export (without any change).

Here is my test project with same filters and items, and three results. If I turn off OpenCL support on my Radeon RX 460 card, then square will no show.

This bug there is under 864 and 869 versions too!

Please check this!

I can't even do the export on either file. It just sits at "exporting" Something isn't right here

Hello @mykee,

I can export your sample file as a JPG file without any problems either with and without Hardware Acceleration.

There is a new driver for the Radeon RX 460, maybe the driver fixes the problem.

 

Cheers

Sorry guys, I have latest driver, and generated with this "pixelate" image. I have Radeon RX 460. This will be a cascaded Live filters problem. I mixed with groups, masks too, with simple trees have no problem, or I use software based render (no GPU), but without acceleration I get 100% CPU load with this project.

I tested with RC1 (version 900) and bug is there. But I found what generate this bug!

I have an Unsharp Mask layer in a Group, and if I turned off this, then generated image will perfect! If turn on this layer, then JPEG export will buggy.

Drive link is same with projects and samples: https://1drv.ms/u/s!Ar9GB-v89284gs0nuOICX591tkedCQ?e=67x372

I can finally reproduce this problem! Not sure why I couldn't before, but anyway, here's what my JPEG export looked like:

Interestingly, I also get corruption in the thumbnails for the history:
