Summary0002911: Ardour Window Twitches Around When Performing Mouse Clicks
DescriptionI believe this was introduced a few minor versions ago (was not present in 2.7.*).

When I click my mouse to do anything from using the menu to dragging a track, the window will jump one pixel to the right, then to the left on the next clip.

I have noticed that Ardour is one or two pixels too large for my display when I unmaximize it. I cannot resize it to make it smaller, so it goes off the screen a very little bit. Perhaps this is related.

I attached a short demonstration video.
Additional InformationI am using Ubuntu 9.10 Karmic. I am using Compiz, but when I use Metacity with no effects turned on, Ardour does not even maximize so I cannot see if it is reproducible there.

Please excuse the crudity of the picture as a regular screenshot wouldn't capture the problem, but if you notice, Ardour will actually run itself over to the next desktop when maximized.

I would classify this as minor now as it really does disturb my workflow. When I try and click on small objects (such as the faders on the tracks), a lot of times the click will miss because the display was wrong by one pixel.

Same issue here - even on a 1280x1024px screen the main window is about 10px too wide. So it keeps flipping back and forth with every click.

When I disable Compiz, the main window could be maximized, but it is offset by about 5px.

Adding another screen from an old PPC iBook running Ardour 2.8.2 on Ubuntu Karmic 9.10 (XFCE).

Seems this is a dupe of bug 0002950:

However, I am using a 1280x1024 monitor. Can we not see the fonts scaled a smidgen by default, as that was the solution to the problem?

its not *directly* related to font size - it all depends on the real and the reported DPI of your monitor. we've found it more or less impossible to find a way to accurately know how large a given font size will be in pixels, and this is by design - a 10pt font needs to be a different number of pixels depending on the kind of display it is used on (think a small mobile PDA/phone versus a projector).

the default font scaling in ardour is "none" (i.e. we use the natural scaling that the font handling system uses).
