3.0 M1 In some situations, the Display runnable queue can get floaded by posted redraw Runnables from various editor UI elements. Typical situations are large (possibly automated) updates of text documents such as 'replace all' and 'format'. Typically rulers and painters detect they need redrawing upon receiving an event (AnnotationModelEvent, TextChange) and post a runnable. There is no check done for whether there already is a pending redraw request in the queue which has not been executed yet. We have put it code to avoid this in LineNumberRulerColumn. Similar checking should go into the following classes: - ChangeRulerColumn - OverviewRuler - AnnotationRulerColumn - PaintManager
Adding my name to the cc list as we are now tracking performance issues more closely. Please remove the performance keyword if this is not a performance bug.
Have the other places where anti-flooding code should be added been fixed?
The bug is still open ;-) [and I've just checked the code].
Done for OverviewRuler.
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.
