Don't know if it's my Video-Card or StellarUF related:
When switching to Desktop and returning to WoW, the background of the pet-portrait get's mixed up with weird colors.
Sometimes with activated 3D-Models you see a static image behind the animated pet-portrait aswell.
No Problem, i've to thank you aswell for trying to fix this bug, since i like StellarUF for it's simplicity and don't want to switch to an other with useless features overloaded UnitFrame :)
Your latest fix solved the Problem on my Paladin for good, but on my Hunter a new funny 'Bug' appeared:
When you dismount, your Pet appears sometimes as "Unknown" or like in the Screenshot with it's name as Class.
It's not annoying in any way, i just wanted to tell you. Error-Alert/BugGrabber did not displayed/recorded any problem with StellarUF this time.
Thanks for the Update, but it only partially fixed it.
Now i can't reproduce the bug in a Major City (like Shattrath), only in other areas (like Terrokar Forest). The funny thing is, when i'm playing with an other character (hunter for example) i don't have these issues, even the Aura-Timers are working correctly.
I've sneaked into the core.lua and found some spells related to a range-check, maybe this is causing the issue on my paladin? Since i'm playing with a german (deDE) client, i've tried replacing the spells with the localisated ones, doesn't help either. Maybe here's a problem with those spells, since the 2.4 patch changed some spell-related stuff (replacing spell-names with spell-id?)?
Anyway, i'm trying to narrow things down, like resetting Interface and WTF Folders.
Yes, it happens all the time. I've just tried logging out, deactivated every Addon i have, only StellarUF running by itself, the bug is still there.
Sometimes it appears it's okay for a while, but if you switch targets very often it's happening again. Just reproduced it after the ~10th target-switch.
