SUMMARY
I chose the general component because I'm not sure what all the backend stuff
means, but tl;dr, when I have 2+ PDF tabs open, Okular doesn't switch between
them properly. The wrong PDF gets stuck on the screen, and I have to close and
reopen the app to fix it.
STEPS TO REPRODUCE
1. Open a PDF in Okular
2. Go to Settings > Configure Okular > General > 'Open files in new tabs'
3. Open another PDF if 2+ aren't open already
4. Click through the different PDF tabs a few times
OBSERVED RESULT
The main display for, say, PDF A will display the pages from the previous PDF
you were viewing, PDF B. The thumbnail view, page count, and table contents
will show the correct info for PDF A, but the main display will not. The
display will also be frozen, so scrolling up and down or clicking the arrow
keys won't do anything.
EXPECTED RESULT
When I click on the tab for PDF A, I should see PDF A in the display, and so
on.
