Performance Problems on Ubuntu 11.04 when using Unity or Gnome Shell #76

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Compile the latest git on ubuntu 11.04
2. Start a Unity or Gnome Shell Session (Gnome Shell has to be installed)
3. Start aseprite
4. Experience some lags on mouse and dialog windows

What is the expected output? What do you see instead?
Normal performance like on Windows 7

What version of the product are you using? On what operating system?
I tested both the 0.9 release and the current git 12.02.2011 on
Ubuntu 11.04 using r600g driver (Open Source radeon gallium3d driver)

Please provide any additional information below.
Could be an allegro problem?
The lag was only slightly noticeable when using unity 2d.

You can try to start ASEPRITE in a separate Xserver like this:

1. open tty1 with [ctrl]+[alt]+[F1]
2. run 

$> xinit aseprite -- :1

(assuming aseprite is in your PATH, else supply the full path)
3. aseprite should now run on xserver:1 and in fullscreen (maybe supply screen 
resolution manually)
4. use [ctrl]+[alt]+[F7] to switch back to your normal window manager and 
[ctrl]+[alt]+[F8] to switch back to aseprite.

This might reduce the lag a little, without needing to switch to xcfe or 
2dgnome every time you want to pixel around.

The issue for the high cpu usage of the Xserver when running ASEPRITE 0.9.* 
seems to be the screen scaler used to artifically reduce the resolution of the 
programm to address the small scale of sprites.

On Ubuntu 12.04 even with Xfce the Xserver goes mad when using the default 
setting "ScreenScale = 2". Changing the value to "1" makes the programm run 
without any significant cpu usage by Xserver - and consequently more fluid.
