@leocg , I just updated Opera on my Linux Mint 19.1. I don't need to replace libffmpeg.so. Video works fine.

@emoxam , I use 57.0.3098.116. I have no problems with video. To be more correct, they exist after update of Opera. But I manually replace codec. After that video works fine. To fix video issues look here: https://forums.opera.com/topic/30254/video-playback-issues

@emoxam , no, it's exactly maximized. No special tweaking. The same thing with Opera is in my test installation of Linux Mint 19.1 Cinnamon on VM that runs under Windows 10. One thing, I have a --start-maximized key in Opera shortcut. But I don't remember that I changed it by myself.

@emoxam said in there are no “minimize”, “expand” and “close” buttons on the top panel:

No matter what selected at cinnamon theme.

Linux Mint 19.1 Cinnamon. Maximized view of Opera:

@emoxam , I use Linux Mint 19.1 Cinnamon. Opera works normal. I have four buttons at upper right corner - Tab menu, Minimize, Restore, Close. It looks like Windows 10.

This problem appears every time I update Opera. I'm using Linux Mint 19.1. But this thing was in 18.3 too. While updating, Opera replaces libffmpeg.so, that doesn't play videos. To fix this issue just replace libffmpeg.so in /usr/lib/x86_64-linux-gnu/opera with the same file from /usr/lib/chromium-browser. After that video plays fine.

The visibility of the top title bar is a feature of windows manager of a linux distro. F11 key opens current page in full screen. All open tabs disappear in this way. Maximized key in launcher doesn't resolve this problem. I have top bar in Linux Mint 18.3 Cinamon too. In xUbuntu there is no top bar by default. But you can enable it in windows manager tweaks in the system settings.

Yesterday, I noticed that nearly five new bookmarks appeared in Speed Dial. That were Google, Yandex, Booking. I don't want to see them in my Speed Dial. I think that it is not a good behavior of browser.

I'm using Linux Mint Cinnamon 18.3 with latest Opera stable. I have no problems with VPN. It works fine.

Hello! I installed last official version of Opera from Google Play. My device is HTC One M7 with HTC stock firmware based on Android 5.0.2. I noticed that Opera drains my battery too much. In the Power - Battery Usage - Screen Off on my device I can see that Opera uses nearly 50% while the screen is off. I don't set synchronization to my Opera account. I only have two tabs open. I think it's not a good thing.
