Can confirm on my opera 108.0.5067.10, win 10, all my personalized searching engine were deleted, and I also notice that card mute is broken, when you have a few pages like youtube, muting one card can mute more other card, and you can't un-mute one card, it will un-mute all muted card, closing and re-open card or refresh it doesn't fix it.

For now it's work, but Tabs drag and drop between windows doesn't work,
what with that strange empty space between tabs and upper edge of screen ?,
and why did you remove home button ?.

@leocg All I get is what in attachment screencap, clicking on show more info do nothing,

@leocg It's means I get the attachment message when I try go on my gmail, and it's only happent on opera after last update, it didn't hapend in previous build or on other browser I'll try, and it's only happens for gmail, other google services work normaly.

@leocg That I can't get normaly on my gmail, before update gmail work without any problem, I chceck it on others browser and gmail works normally there, this only occurs on opera 75.0.3967.0

Have a problem with gmail,
sing out, and sing in didn't help, using "try again" a few time allow me to go gmail, this problem started with this update.

fb messenger sometimes bug out like that

@ralf-brinkmann Same here, but if I switch between tabs it's help with this bug.

@leocg Just check with disable fdm, and fb work ok and after enabling again flickering is back with that checkered background

FB on opera is broken https://youtu.be/vX-41S3kT-o background is flickering when forced dark mode is on.
