xemacs and compiz fight over size increment hints when maximized

[Roger Binns]

Binary package hint: compiz

Using Intrepid as of an hour ago upgraded from Hardy. If I enable compiz and then run xemacs and then maximize xemacs, the entire desktop becomes pretty much useless. One entire screen of my dual screen setup grayed out in the way that compiz does to unresponsive programs and then I couldn't click anywhere or move any window. Only going to a console and killing compiz.real solved the problem. top showed X using most of the CPU (~75%) followed by compiz ~15% and xemacs ~7%. It should not be possible to hang the entire desktop like this.

The single most likely cause is an issue in xemacs. Basically it always wants to resize to a multiple of the size of a character whereas the window manager wants it to be the width the screen. The two programs then have a battle over what the size should be. Bug #3982 from 2.5 years covers this issue in xemacs itself, which still isn't fixed in xemacs-intrepid.

This bug report is that compiz makes a bad situation worse by effectively disabling the entire desktop even though it is only one program that is misbehaving.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.

Go ahead and close this since even if I went to the trouble of reconfirming, nothing would be done about it.

Sort of confirmed in karmic. It doesn't cause the system to become unresponsive but you can clearly see compiz and xemacs fighting over the size of the maximized window.

[Daniel Hershcovich (daniel-h)]

Indeed - still present in Karmic.

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. It would help us a lot if you could test it on a currently supported Ubuntu version. When you test it and it is still an issue, kindly upload the updated logs by running apport-collect <bug #> and any other logs that are relevant for this particular issue.

This bug has been present in ubuntu since at leaast 10.04, and is still present in 12.04.

[Xolotl Loki (xoloki)]

I will add that the bug is present in previous versions of ubuntu even without compiz (e.g. uncomposited xubuntu 10.04) ; I have not tried 12.04 without compiz, thanks to the beauty of the new Unity interface.
