Created attachment 5465 Diff file with the bugfix package: xfce4-panel-4.11.0 plugin: tasklist Minimized icons in the tasklist are rendered with a certain transparency factor, but actually this doesn't apply to grouped icons. To mantain a consistent behaviour, when "all" the windows inside a group are minimized the grouped icon should be transparent too. I attached a bugfix. Cheers, amigamagic
Created attachment 5466 Diff file with the bugfix (v2) Fixed another bug: let's suppose you selected to display only the minimized icons in the tasklist. Now if you open a new window of a different type from the ones currently in the tasklist, and then minimize it, its icon will be displayed without transparency. This is inconsistent with the expected behaviour, so I fixed it.
Pushed to git (v2). It fixes the second issue (transparency of minimized new windows) but the first one is still there (grouped icons are are opaque even when all their windows are minimized).
Please try to git apply --check yourpatch.patch before submitting, to spot and remove all trailing whitespaces :-)
Otherwise, just as for Andre: neither patch 5465 or 5466 fix the reported issue. They appear to be doing nothing. Amigamagic, could you please tell us how you tested this patch?
I've rebased this patch on top of current master, but I still see at least one issue I would like to fix before merging this: - when a single window is minimized and you then open a second window of that application, the icon remains 70% translucent, so there's at least one unhandled signal/case (active_window_changed or whatever) - the exo stuff should be replaced by style-classes and something like "button image { opacity: 0.7; }"
Ok, part one is done. I'll try to replace exo too and then push this.
