Emacs window doesn't get redrawn when switching desktops

[Johan Tibell]

Binary package hint: emacs

When switching from the desktop where Emacs is running and back results in the text inside the window not getting redrawn. Could this be some sort of graphic card buffering issue?

[Johan Tibell (johan-tibell)]

This is for Emacs 21.4a-3ubuntu2 using Dapper. I've attached xorg.conf.

I'm not sure I understand what the problem is. Is it that when you start emacs, then switch to another desktop and switch back, the initial welcome screen isn't displayed? Or is the window completely empty? If so for how long? Could you provide a screen shot?

[Johan Tibell (johan-tibell)]

I can open a file (say Main.hs), the text is displayed normally. I switch desktop and when I return Emacs looks normal except that all the text is gone (i.e. the content of the buffer part of the window is all white, the scrollbar etc is still intact). If I move around the cursor the characters get redrawn as I move over them.

Almost definitely an X server bug!

Johan, could you test to see if this is fixed in newer versions of Ubuntu (such as Feisty), so we can see if it is a Dapper-only issue?

[Johan Tibell (johan-tibell)]

I don't have the same laptop anymore so I can't repeat the test. On my new machine with Feisty it works just fine.

Thanks for the information, closing the bug!
