SUMMARY
As per title, previews often fail to show up for me, they're just blank. The
worst issue is its very hard to reproduce: there seems to be an almost 50/50
chance whether they'll appear or not. If you have a group of windows sometimes
no previews are there, sometimes only one is empty, sometimes it'll take 1-2
seconds to appear.
But most often, if no previews appear, you have to let them disappear and click
on the plus or hover again and this time they'll be there. I have seen multiple
bug reports about this and many seem to be marked as fixed and yet i've never
found the previews to be reliably working. I was always told having minimized
windows not showing thumbnails was a limitation of X11 and something Wayland
would fix but it's just not reliable.
I'm not sure if the logs contain anything useful but i've attached journalctl
output.
I rely on these a lot so having them working would be grand. Thank you for
reading.
STEPS TO REPRODUCE
1. Create a few windows of the same type
2. Hover or click on the plus icon on the icon only task manager
OBSERVED RESULT
empty window previews
EXPECTED RESULT
windows previews are working
