Description Andrey Tarantsov

Steps to reproduce:
1. Connect to a Windows machine using Remote Desktop (note: I'm using Mac remote desktop, can't really check if the same problems occurs with Windows Remote Desktop).
2. Open a big file in Eclipse.
3. Scroll down.

I expect to see instant not-smooth scrolling, but rather it scrolls smoothly, but veeeeryyy slloooooowwllyyy.

Don't know why — while I can't really watch a movie over Remote Desktop (say, with Windows Media Player), at least it's not that slow, and it skips frames rather than waiting for them.

First we need some more info:
1. which build id?
2. which editor?
3. please try with the attached SWT snippet
4. create a stack trace while it scrolls and attach it here

Actually it's still slow with the snippet, but I cannot get a stack trace because the remote desktop does not process any input while scrolling has not completed. Chances are Eclipse is not doing anything at this point, but somehow it has created too many screen updates that somewhy do not get dropped.

I'm using Microsoft Remote Desktop 2 beta, but the problem also occurs with Remote Desktop 1.0.3. I tried filing the bug over it, but they refused to accept it because it is only reproducible with Eclipse.

Using SWT 3.3.0.v3346 - the one available on Europa release day.

Ideas?

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.
