Bug 447610

Could you provide us with some hardware specs? This seems to be an OpenGL or Angle issue with cached playback.

Sure, what specs do you need?

Hi popingsarah,

If you could provide the following information, it would help us quite a lot.
1) Please give us any information regarding your cpu or gpu (model, driver, etc.) so we can try similar vendors or models if possible.
2) If you could provide us a test file, like the one in the video that can have the issue reproduced, that would help with trying to reproduce it on our end.
3) Lastly, please tell us your current settings in the following preferences windows: 
   `Settings > Configure Krita... > Display > Canvas Acceleration`
   `Settings > Configure Krita... > Performance > Animation Cache`

Thanks,
Eoin.

1) In device manager it says: AMD Radeon R7 Graphics (driver version 27.20.20903.8001) 
    But for more specifics in msinfo it says in processor AMD Pro A8-8650B R7
2) I will attach the krita file it happened to (though I will say, the issue is only within krita playback, when it is exported as an mp4, as I did afterwards, you cannot see the corrupted frame). 
3) Canvas Acceleration: 
                                       Renderer- Auto (Direct3D 11 via ANGLE)
                                       Scaling mode- High Quality Filtering
                                       Use texture buffer- on
    Animation Cache:
                                       Cache storage backend- In memory
                                       Limit cache frame size- 2500px
                                       Use region of interest- 25%
                                       Enable background cache generation- on

I tried to attach the krita file but the "add an attachment" feature here says the file is too large.

Thanks for your comment!

Automatically switching the status of this bug to REPORTED so that the KDE team
knows that the bug is ready to get confirmed.

In the future you may also do this yourself when providing needed information.

So those settings don't look like anything I don't have going on in my system. I'll have to see if someone else has hardware similar to yours where we can try to reproduce this issue. One last thing you could try is updating your current driver (it looks like your version is from May of last year, and there might be newer graphics drivers available.) You can also try limiting the frame cache to 1000px and see if that resolves any caching relates issues (it could be that your graphics card is out of memory on longer animations, but in which case we should still probably find ways of preventing this kind of issue.) If the 1000px frame limit works, you could see if on-disk caching at 2500px helps resolve this issue too!

I'm sorry that I couldn't be of more help,
Eoin.

I made a similar test animation but I'm not able to reproduce this issue on either Linux or Windows with various settings.
It could be that I'm on an nVidia GPU, but I had Eoin test it on his AMD GPU and he wasn't able to reproduce it either.

Is this still something that affects you on more recent versions of Krita, Sarah?

For now I'll be setting this to "needs info" /  "works for me", but it's no problem to reopen this bug report if the issue is still affecting people.
