Build Identifier: 20100917-0705 Introduced by the fix of bug 212501, ControlDecoration performs unnecessary redraws in upadte(), since there are no checks whether there is really a need for redraws. For example, if show() or hide() are called, update() is called to and forces a redraw. Even if the decorated control is not visible. In most circumstances that does not matter. But if the UI contains a widget that performs performance-intensive redraws, that might be of interest (like in my case). Since the redraw is triggered on the shell, any visible widget intersecting the area to be redrawn is notified via a paint event. Reproducible: Always
Created attachment 188260 [details] Possible fix I have tested the changes using the snippet from bug 212501 and it seems to work.
Can you please attach a patch/diff (rather than the entire .java file) so that I can take a look at what you've changed?
Created attachment 208483 [details] Diff of ControlDecoration Here is the diff against eclipse version 3.5.2.
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. If the bug is still relevant, please remove the "stalebug" whiteboard tag.
