chromium does not minimize correctly when pcmanfm is also open

[Justin]

Steps to reproduce:

-Open at least 1 chromium window and 1 pcmanfm window
-Minimize chromium

Chromium's inner frame will flicker off for a split second and then re-draw itself. Everything but the window border (if "use system title and border" is enabled) will stay on the screen after being minimized untill you drag another window over it to erase it. This only occurs when pcmanfm and chromium are both open at the same time.

Status changed to 'Confirmed' because the bug affects multiple users.

[Konstantin (xlammail)]

Also LXDE, nVidia prop driver(304.117). Chromium after minimize showing, any new windows redraw chromium dirty part of screen.

[Saikrishna Arcot (saiarcot895)]

This likely has the same root cause as bug #1309076.

[Saikrishna Arcot (saiarcot895)]

Can you try using --ui-disable-partial-swap?

[Justin (razema)]

As it turns out, this was a problem with the nvidia driver. After upgrading to the newest version, 340.24, the bug has been fixed.

Re comments in #7, issue resolved but not a Chromium bug so marking "Invalid"
