R3.0: Restored AppVM menu icons are buggy

[andrewdavidwong]

I restored several AppVMs onto a fresh R3.0 install. Even after using qvm-sync-appmenus and restarting everything several times, many of the KDE menu icons are exhibiting strange behavior: There appears to be no icon next to an entry, but then hovering over that entry causes the icon to appear (but only while the cursor is over it).

I think this may be another case of #1106

Also it may be some KDE icon cache issue... Try removing /var/tmp/kdecache-*/icon-cache.kcache then logout and login.
If this doesn't help, take one misbehaving entry, find appropriate desktop file in /var/lib/qubes/appvms/*/apps, check the Icon key, check if the file pointed there really exists, is the correct icon etc.

I was somehow able to get them all to show up correctly by add/removing entries and changing VM colors, then rebooting.

I think this confirms KDE icon cache issue. The cache is removed when changing label specifically because of such problems.
Maybe we should remove it also after every qvm-sync-appmenus or even any icons modification? I'm not sure how it would affect performance, but outdated/broken icons in KDE is unfortunately quite common problem :(

IME, qvm-sync-appmenus adds a noticeable delay when updating templates, so if we add even more steps, it would be nice if the whole process were not run automatically every time (especially if this particular issue only happens when AppVMs are restored from a backup, which should not happen very often).
