Public bug reported:
Reporting from a ISO Testing Live session, this problem has been noticed with
fresh installation.
Step to reproduce it:
- Boot in a live session
- Open firefox and maximixed it
- Minimize firefox with the buttons in the the top left corner
- The bar appear in a light gray without transparency
- If you open any other window and drag it the bar is refreshed in the normal
appearance
Sometimes minimizing firefox it's possible to notice some gray glitches
in the top left corner. It looks like it's the shadow of from the title
bar not refreshed after the minimizing animation.
Hint: maybe hardware related. Bug reproduced with a Dell Inspiron 1520
(nVidia GeForce 8600M GT) and a desktop pc (GeForce 8600 GTS). Bug not
