Translation text layer blur large and incorrectly offset from expected position #1457
Description
Activity
Hi @schu96! I’ve noticed this issue regarding the translation text layer blur and would like to help resolve it.
I am currently setting up the BookReader environment locally to try and reproduce the offset. Since I'm new to the codebase, are there any specific files related to the translation plugin's rendering logic that you'd recommend I look at first?
Thank you for your time!
Hi @schu96,
I fixed this issue locally by adjusting when the blur is shown. I tested in Chrome, and the blur now stays aligned.Happy to open a PR if you’d like.

@jnakaigen the bulk of the logic for this plugin can be found in the
plugins/translatefiles, I recommend starting thereHi @rajeevroy21 thanks but the intended behavior would be to preserve the translated paragraph background showing over the original text even if the translation is not completed. The cause of this specific issue has been identified, please feel free to check out another issue and submit a PR with a screen recording / screenshot of the fixed behavior
Description
When the translation plugin is active, the blur that covers the original text image is not directly over the text selection layer. This results in an odd period where the blur element is partially off of the page image before it correctly snaps into the right place.
Evidence / Screenshot (if possible)
Expectation
We should expect the blur to be sized and positioned properly over the text.
Context
This behavior has mostly been observed in Chrome and could potentially affect other Chromium based browsers
Proposal & Constraints
It may be best to only show the blur translate layer after models are loaded + after translated text is completed?
