The Linux sync thing

[stefan-reich]

Hi Kirill :)

There is a known issue for Java on Linux, namely that its video buffers aren't always synced promptly (there is some delay <1 s).

This makes, for example, the smooth scroll bar animations appear choppy sometimes. [Example]

Moving the mouse in the window constantly seems to make the animations smooth again.

I have, at times, been calling Toolkit.getDefaultToolkit().sync() explicitly which causes the buffers to be drawn instantly. However, in the case of the scroll bar animation, I wouldn't know how to do that.

Any thoughts on this? It would be nice to see this fixed for sure.

That example is not very useful as it's not a standalone Swing sample.

I'll need a bit more information, and ideally a full sample as well:

• Version of Substance
• Version of OS
• Version of Java
• Specific scenario where scroll bar animations are choppy

Note that scrollbar appearance has been changed quite significantly in the latest 7.0 release

Thanks Kirill, nevermind, it's not worth bothering at this point :-)
