[Support]: Explore > correcting wrong detections > images take very long to load / old images remain visible #22990

Describe the problem you are havingwhen reviewing images to improve the detection mode, the "Next" and "previous" button load the html content immediatly, but continue to show the last image you watched for several seconds 
addendum: clicking next & previous is NOT slow, if you don't use "Yes" or "No" just before clicking next or previous. Slow "next" after clicking yes or no = 4 seconds: Fast "Next" without clicking yes or no first VersionSysteem 0.17.1-416a9b7 What browser(s) are you using?No response Frigate config filemqtt:

I believe this is due to thread contention from submitting to Frigate+, this was fixed for 0.18 in #22426 |

Yes, that appears to be the case. Truenas apps doesn't offer me 0.18 yet, but it's good to know that it'll be fixed in the upcoming update! Thanks! |
