Hello, Not sure it helps, but I observe the same here (xfwm4 with compositing + mesa 18.1.1-1 fail, and a white screen is displayed) but only with xfwm4 in experimental (4.13.0-1). Unstable version (4.12.4-1) is perfectly fine with mesa 18.1.1-1 (intel graphics HD4000, CPU generation is Ivy Bridge, and modesetting driver is used). Yves-Alexis, which xfwm4 version do you use ? Best regards, Pascal Dormeau
