@sgunhouse Of course you can add Opera to the taskbar. Right click on launcher.exe -> Pin to taskbar.

It would be really great to override that fantastic Chromium invention, that it is not possible to select/copy text from username/password textboxes under passwords settings page. Also, the textbox is too small. If text is longer than textbox, I can't see the end of text.

It is Opera bug. I wrote in other thread, I have two virtual machines with Fedora + Xfce. First VM is not updating Fedora 22, installed maybe 3 years ago and second is always uptodate Fedora. Opera on first virtual machine HAD all buttons. And every new version of Opera removed some buttons. Xfce was not changing, only Opera was changing. So the missing buttons is matter of Opera and not desktop manager. And we know how often is Xfce updated...

They do not want us to use their browser...

No, pure default installation. I didn't found any flag regarding titlebar or buttons.

I have old Fedora 22 in VM, not updating. Only Opera is updating there. Nice couple of versions before, there were all buttons. After some time, only X was visible. Now, nothing is visible. I installed in second VM Fedora 26, complete default XFCE, with latest Opera, and now, only X is visible when maximized.

I use XFCE, and all buttons are gone, when window is Maximized. I do not want to go with mouse acros whole screen to taskbar to minimize it, I do not want to go to Menu and click Exit. What's wrong with UI designers these days. Removing basic functionalities which works for decades.

DirectDraw has also few options of aliasing.
Have a look:

Yeah, code for GDI cals is removed from chromium. But text rendered through DirectDraw can be modified by Opera devs probably.

There are few modes of aliasing with DirectDraw which can be set.

Ok, I found that I need to enable Disable NPAPI plug-ins in flags. How can I set to open it automatically? Now it always prompt me for downloading .ica file.
