Description Soukyuu 2016-05-11 20:21:28 UTC

This seems to only affect the icon-only task manager, and only the pinned icons. I was able to reproduce it with Konversation, Chromium, deadbeef and dolphin(4). The application starts fine, but the entry is missing the icon. Hovering over the entry fixes the icon and it stays displayed until the next time I start the application.

Reproducible: Always

Steps to Reproduce:
1. Select "show a launcher even if not running" for any of the applications listed above
2. Close the application
3. Start the application by clicking on the launcher

Actual Results:  
Entry is present, icon is missing

Expected Results:  
Both entry and icon are present

I noticed this with 5.6, it was definitely fine on 5.5 There is a similar bug #362106 but it is NOT fixed for me. Arch linux x64, up-to-date as of yesterday, nvidia 260GTX w/ proprietary 340xx driver.

Reproduced.

Comment 3 Eike Hein 2016-05-12 07:49:16 UTC

I can't reproduce it reliably however -- only happens in about 1/20 starts.

Don't read empty icons from config-stored launcher URL.

Fix icon never turning visible when transitioning from startup.

Also stops blanking the icon while running the startup throbber, which
we used to do to hide ugly morphs from launcher to window icons, which
we no longer need to do since we default to launcher icons.
