I'll try to elaborate a little:
The issues started in v.50:
- In Theater View I notice some artifacts in the letters when rolling the items in the main menu.
- At the Playing Now page, the position "dot" doesn't move continuously but abruptly, and during the artist slide show I get intermittent drawing Direct3D errors (which last less than one second on the screen).
- If I enable the old Playing Now plugin, which overlays some info of the current track on the screen, it also suffers some kind of artifacts or ghosting and it worked perfectly in all the previous versions.
In some way, the experimental exclusive mode Theater View drawing seems to be causing instability in my system (Win XP), even when it is disabled.
