reader mode, no preview #1364

Closed mexsudo closed 3 days ago

Discussed in https://github.com/lwindolf/liferea/discussions/1363

Originally posted by **mexsudo** May 15, 2024 Debian Stable, Mate the "preview" is blank in reader mode and also when I in browser I still have the ability to open in external browser. ![Liferea 2024-05-15 08-49-26](https://github.com/lwindolf/liferea/assets/7226539/31e25baf-68f0-4ea9-93ec-6bf7dbf9dd7c)

If you have an NVidia graphics card you might be affected by #1308 which is not caused by Liferea and has a workaround.

You can check this by using GNOME web (epiphany) to load a page. Does it have the same problem?

mexsudo commented 4 months ago

the NVidia workaround. nope, same result

I don't have epiphany installed

lwindolf commented 4 months ago

Ok. Then it can be a Liferea problem. Can you start from a terminal with

liferea --debug-html

The you will have a new context menu option in the item content pane "Inspect". Clicking it will open the Web developer tools. Once you opened it please navigate to another icon and check for errors in the "Console" tab.
