XnView Software

To me it's still unclear who created the database or those EL8 files and how.

Well, only for "lucky" owners of ...

0. upload one EL8 file
1. make a screenshot of the image displayed on screen instead of exporting EL8
2. contact the support and ask them how to export BMP or PNG or what this EL8 is supposed to be
3. provide more details in English language (name of the bugged software? paid?)

Does crash for me

PS: XNVIEW 1.70.3 from 2004-Jun-21 doesn't crash, it rejects the file

Doesn't crash for me.

extremely poor performance rendering Canon Raw files? It's a great program otherwise

Please supply an example file and performance details XN vs other program.

Performance for NEF files is also bad and XN is unresponsive:

I'm getting best results with Tolerance 21 ... but AutoCrop is not smart ... you have to find out the background color (here white, no problem) and the tolerance (big ...

OK, they finally added the WEBPLL files ... Sigi: RIFF????WEBPVP8L

Still buggy in 1.99.1. Warns about multiple pages, but neither animation runs, nor I can see other frames as pages

Same in 1.99.1

Worx for me with 1.96 and 1.99.1 :-)
