I get newsfeed from Opera blogs in this feed, the address is an HTTP link.
If I write an answer in this blog but go in via an HTTPS address, the post is gone (all)
Example:

A blog post and two different commentary trees.
This is stange, better only HTTPS and all HTTP redirect to https.
And my comments from this blog have been deleted…

Since Opera 53.0.2885.0 developer (also Opera 53.0.2893.0) i get a system message when opening a URL if it comes from an external program (IRC link, help link from LibreOffice, etc.).
German:
Der vorgegebene Internetnavigator konnte nicht gestartet werden.
Eingabe-/Ausgabefehler
English:
Failed to execute default Web Browser.
Input/output error
Site opens, but with the stupid system dialog.
No dialog with Opera developer 53.0.2880.0, Opera stable, Firefox, Vivaldi
The dialog only opens if Opera Dev ⋝ 53.0.2885.0 is the default browser.
command line:
exo-open URL with dialog (exo-open starts the default browser)
opera-developer URL without dialog
OS: Siduction 64bit
DE: Xfce 4.12
Can anybody confirm that, or what is the mistake?
With Opera developer 51.0.2830 works gpu, all my issues from above have been fixed. 
@loup001
Do you have NVIDIA, if so, can you check on opera:gpu if the hardware support is enabled?
And how does the http://slither.io site work for you or very slow?
With me the GPU support Opera Developer 51.0.2809.0 is corrupt (see my posting above).
My result from opera:gpu: Opera_51.0.2809.0_gpu.pdf
OS: Siduction 64bit, NVIDIA 9600 GT (nvidia-legacy-340xx-driver)
