LXDE Forums

I've been using LXDE for a long time. First in Lubuntu and now with Debian 9.4 Stretch. My Desktop Pages always showed icons for the opened applications in each desk. They have now suddenly stopped appearing. Has anyone experienced this problem? Will appreciate a solution or workaround.
Thanks.

You didn't give us a lot to work with. Try right clicking any open space on the lxde panel and select "Task Bar (Window List)" Settings. Place a check mark on "Show windows from all desktops" and then close. That will list of all open applications on all of your desktops.

I'm not using the Taskbar, just the Desktop Pager. Anyhow, I added the Taskbar and looked at the Settings. Found that "Show windows from all desktops" was already checked. The problem is that the Desktop Pager sometimes show icons and suddenly they are replaced by a rectangle. This irregular behaviour is what I want to correct, if possible.

Do you mean this?

No, I'm using a narrow vertical panel on the left edge. I set a 48 px wide margin there. I do not need text, just the icon of the topmost app in each workspace to appear. Unfortunately, this does not happen in every session and sometimes I get only rectangles instead of icons. See attached capture.
The annoying part is that some sessions have icons and others do not. This is aleatory and I could not associate this behaviour in any way.

I do get Icons.
But if the window in question is too small the icon disappears.
The windows in your screenshot seem to be too small for icons to appear in them.

Well, the funny thing is they do appear sometimes (just like now) with space to spare. Sometimes they do not and, as said, the behaviour is uconsistent.

I think it's consistent.
Try this:
- Maximise Firefox - do you see an icon?
- Now resize the Firefox window to make it very small - do you see an icon?

Yes, I see what you mean. It works just as you describe. Icons disappear when the window becomes too small to contain it.
Will keep on checking as I still recall not having icons displayed even with maximized windows. If that happens I'll report again. Thanks for now.
