Attached is another screenshot from Eclipse. This one happened after scrolling. The first four lines of the command_new function body are missing completely (the second line of that block is empty anyway, however), the fifth line is clipped. Also note the discoloration of the first two missing lines and the one preceding it.
** Attachment added: "Missing lines in Eclipse" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1418679/+attachment/4313884/+files/Screenshot_Eclipse.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1418679 Title: Multiline text controls occasionally get corrupted on refresh Status in xorg package in Ubuntu: New Bug description: I have recently updated from Ubuntu 12.04 (32-bit) to Ubuntu MATE 14.10 (64-bit). After upgrading, I find that some text controls have a refresh issue that seems to get triggered either by scrolling or adding a new line when the text already contains more lines than can be displayed at a time. This happens infrequently and is not always reproducible. The issue is that some lines in the text control show as blank lines. I have noticed this happen in the following applications: * Eclipse 3.8 * Thunderbird (various versions) * Firefox (various versions). In Firefox text is occasionally clipped, but not necessarily at line boundaries. Other applications seem fine, it might be related to the widget toolkit (OTOH, the apps above use two different widget toolkits – Eclipse uses SWT while the other two use XUL). I am also seeing a different kind of output corruption in Terminal, which may or may not be related. Similar to the above, it happens when I press ENTER while at the bottom of the terminal window. I have seen the same issue on a second computer running a custom Linux build based on Kubuntu 12.04 (32-bit) with some components (including the kernel) being later versions than what is included in 12.04. A third computer, also running Ubuntu MATE 14.10, does not seem to have this issue. This seems to be a bug introduced into Ubuntu after 12.04, though I can't tell which component is at fault. It is possibly related to https://bugs.launchpad.net/ubuntu/+source/openjdk-7/+bug/1239607. I will post more details (including screenshots) soon, so bear with me.
