Possible Bug with Window Scaling in 2.56a under Ubuntu 10.10

The Youtube video should be converted soon, but until it’s live, heres the description:

I noticed this behavior in earlier versions of the 2.5x series, but I did not have the time to check the tracker to see if it had been mentioned or fixed already. I would like to confirm its existence on other builds/platforms. I am using Ubuntu 10.10 on an Intel Core i5 with an NVIDIA GeForce GT 330M using the NVIDIA binary drivers.

Steps to recreate:

  • Run Blender.
  • Scale the window down and up vertically and horizontally by grabbing the lower right corner.
  • Eventually, the scaling function gets corrupted and will continually cycle the vertical scaling no matter which direction you move the mouse.

It appears that the panels don’t have a minimum size setting, and are literally getting scaled down to zero and disappearing into oblivion. I’m not sure what might be causing the large black area to appear.

I have also tried running Blender 2.56a Win32 through Wine, and I can achieve the same effect.

Edit: Here is a screenshot of the behavior from the video:
