Thanks for the update. I can confirm the fix. I also can confirm that the domain matching feature does not work. I get only the item for the Firefox sync login.
Its all good, I fixed it by setting the following:
QT_auto_screen_scale = 0 and QT_screen_scale_factor = 1.
When I had set to fractional scaling like 1.25 then I noticed a large amount of lag and some pixelation but setting it to 1 has fixed the issue.
I want to provide an update.
On the nightly version of Firefox the flickering has been fixed.
Although the website domain does not seem to be getting passed to Enpass afterwards.... It never matches any of your logins you have manually search through the full list
