❗Problem

If you are working with atvise SCADA 3.11 or below versions, you might experience an issue regarding visualization while using the web client in Chrome/Chromium-based browsers since the v138 update.

The issue applies to the following when viewed in Chrome/Edge v138 or later:

atvise® Server / Visualization versions up to and including v3.11.
webMI pro versions up to and including v2.40.
Any webMI SDK visualization generated with atvise® builder ≤ v3.11.

✅Solution

Temporary Workaround

Steps:

To fix this, you can go to chrome flags and disable the Deprecate the unload event flag by accessing to the following url:
```
chrome://flags/#deprecate-unload
```
This feature can be accessed in Edge as well, if needed.
```
edge://flags/#deprecate-unload
```

Remember to restart the browser for changes to make effect.

Upcoming atvise® v3.12 (and later) and future webMI releases will be adapted to the new Chromium lifecycle model and will officially support Chrome/Edge v138+ without requiring the flag.
