@sgunhouse I have unpacked the Opera Developer deb package and edited its control file to make Opera Developer depends from libcurl4 OR libcurl3, giving preference to libcurl4. For now, Opera Developer is working as before. I've noticed no issues yet and downloads are working fine.
When I tried to update Xubuntu 18.04 Bionic Beaver today, apt asked to remove Opera (Stable, Beta and Developer). The packages that apt is trying to remove are:
opera-developer deinstall libcurl3 deinstall opera-beta deinstall libxmlrpc-c++8-dev deinstall libxmlrpc-core-c3-dev deinstall libxmlrpc-core-c3 deinstall opera-stable deinstall libxmlrpc-c++8v5 deinstall
Google Chrome is being updated and apt is not asking remove it. This is the complete list with the updates and installs:

I have a Alcatel Pixi 4 (4"), model 4034E, and I noticed that when I watch a video using Opera the CPU increases, as expected. However, after I finished watching it, the CPU may not reduces the usage, keeping whatever usage it had while playing.
Example: if to play a video Opera needed 50% of CPU, if I change the open application or after I finished watching and closed Opera, it still uses 50% of CPU. Consequently this causes heat and drains battery quickly.
This is not something consistent, as this doesn't always happen and I don't know what triggers it, but I have seen this happening only with Opera.
The workaround I have found to reduce the CPU usage after watching a video in Opera is to open a media file on the Chrome browser. As the base is (apparently) the same for both browsers, somehow Chrome solves the problem Opera causes. It doesn't work 100% of times, but after a few attempts this work.
Opera version is 44.1.2246.123029
I have noticed Opera Developer is using much more CPU than Opera Stable when there is media content in the page. An page that uses 3% of CPU on Stable uses 10% on Developer. An page that uses 8% on Stable uses 30% on Developer.
When there is no media content I have noticed no significative difference.
Version: 52.0.2845.0 developer
Operating System: Xubuntu 17.10 (x86_64; XFCE)
My Windows 10 version is 1709 (Fall Creators Update), so it should have the capability.
Unfortunately the flags had no effect and still couldn't use the hardware capabilities. What I noticed is that when the video is in full screen, the GPU Processing usage is significantly reduced and the Video Processing increases to numbers close to Google Chrome.
What I can be sure is that hardware decoding capabilities exist and work on both Windows 10 and Xubuntu 17.10, they only aren't being used.
Regarding audio difference on Xubuntu, the best word I could find to define the sound is "muffled". I have noticed this difference on every file with audio encoded using opus. To encode I use, for example:
ffmpeg -i INPUT -acodec libopus -application audio -b:a 320k -vbr on -f ogg -flags +global_header OUTPUT
This is very noticeable with high frequency sound, some instruments become completely inaudible. Maybe a voice optimization which degrades sound fidelity?
I have found why it was not possible to seek the WebM videos. Chrome and Opera expect the server to answer the requests with
Accept-Ranges: bytes, the server was configured wrongly.
Is there a way to test Opera with the vpx decoding enabled, to see if it is really slow?
opera://gpu, on the part where it says Problems Detected, there is:
VPx decoding is too slow on Intel Broadwell, Skylake, and CherryView: 616318 Applied Workarounds: disable_accelerated_vpx_decode
Unfortunately I can't read the bug description as it asks for an account.
But if Chrome has it working, wasn't that solved?
Is there some answer regarding the other two problems (particularly the first)?
Edit: Chrome has the same
disable_accelerated_vpx_decode workaround, so why there is a so big difference in graphics processing usage between Chrome and Opera?
Hi, I have changed the repository and the download speed increased from 8 kB/s to 200 kB/s for Opera Developer, this is a great improvement.
I noticed the instructions are not updated to the new address.
