Estou tentando adicionar algumas coisas extravagantes à minha área de trabalho, e o que estou lidando agora é definir sombras em todas as janelas. Estou usando o Compton Composite Manager e está tudo bem, mas veja as seguintes imagens:
Se uma janela tiver cantos normais, tudo está ok, mas quando estou tentando arredondá-los, o efeito estranho ocorre.
Estou usando as unidades proprietárias de teste Debian, openbox autônomo e nvidia graphic (7600GT). Eu instalei os seguintes pacotes:

Versão do kernel:
$ uname -a
Linux morfikownia 3.11-2-amd64 #1 SMP Debian 3.11.10-1 (2013-12-04) x86_64 GNU/Linu
Alguém sabe por que isso acontece e como corrigi-lo?
Eu olhei no arquivo de configuração do compton e havia algo assim:
clear-shadow = true; # Zero the part of the shadow's mask behind the window (experimental).
Experimental você diz? Então, eu configurei isso para false, e agora eu tenho janelas arredondadas muito bonitas com sombras:
Há também outra maneira de corrigir o problema. Você pode definir as seguintes opções na configuração do compton:
clear-shadow = true;
shadow-ignore-shaped = flase;
