Apache OpenOffice (AOO) Bugzilla – Issue 65270
Windows get rendered multiple times on 1 action

When I connect to my university over ssh and start openoffice from there, I notice that for almost every button I push or other thing I do (except typing) all the buttons and menus get rendered 2-3 times even when only one of them has been used. I'm not sure why open office is doing this but I think the whole suite should work somewhat faster when you clean this up a bit. If you want to see what's happening clearly just open a ssh connection over say a 1-2Mbit connection (I work at 2Mbit), start open office, add some formulas, save your document, muck around a bit and you will see what I mean. When you run open office locally this is probably not very noticable but I think it should make the application feel more responsive/quicker even then.
One thing here is that depending on the desktop theme controls can change their apperance on mouse over, so if you just move the mouse around you will necessarily create painting of controls. pl->tm: i don't know where to put this other than framework. If there are any controls that paint too often without need please file issues for those.
TM->requirements: please have a look, thanks !
Any news yet? The multiple rendering stuff does not have anything to do with mouseover btw. It might be that mouseover triggers it too now and then, but a simple action like entering a formula and leaving the formula editor by clicking somewhere in the text already makes the button bars render two or three times. Furthermore: It's not like there are "any controls" which paint too often, it's basically all of them. Well maybe not the menu bar (file, edit, etc) but all the buttons are.
