Description Martin van Es 2019-12-18 09:06:59 UTC

SUMMARY
Plasma Pager only shows thumbnails of top screen when using multi-display setup.

STEPS TO REPRODUCE
1. Attach extra monitor to laptop, configure to display above laptop
2. Place some windows on external (top) and laptop (below) screen

OBSERVED RESULT
Both screens are reserved in pager (layout adapts to new situation), but only windows on top screen have thumbnails.

The same happens when the display layout is left-right, but then pager only shows thumbnails for the left screen.

EXPECTED RESULT
See thumbnails of all windows on all screens in pager

I'm seeing the same on Fedora. Left hand screen (laptop) is fine, right hand screen (external) has no window outlines.

Patch that reverts pager to 5.16.5 version

Seeing the same thing (also on Fedora 31).  The attached patch, which reverts the pager to the 5.16.5 version, "fixes" the issue.
