Re: [Rosegarden-user] Bad graphics on Ubuntu 11.04 with RG 11.06

[D. M. M. <mic...@ro...>]

The user posted a screenshot to the list, but it was too large to approve.  If 
other people get involved on the development side, I'll just have to forward 
them copies.  What it depicted was a relatively normal looking Rosegarden main 
window, except that the segment canvas area was totally wrecked from obviously 
using some random chunk of memory for a video buffer.

Given that we've never remotely seen anything like this in the field before, 
the first thing to try is to change the Qt graphics system.

It looks like you are already using "safe" (seguro) graphics, but the only 
other choice to try is "fast" (rápido) graphics.  We offer only the two 
choices, because those were the only two Qt graphics systems that proved 
reliable enough for field use during our experiments.

Go to Editar -> Preferencias -> Caldidad del rendimiento gráfico (Edit -> 
Preferences -> Graphics Performance) and change the option.  Exit out of 
everything and start Rosegarden again.

If that didn't fix the problem, I'll have to try to get Chris Cannam involved, 
because I don't have the computer graphics chops to begin to guess where all 
of this might be breaking down, or how.
