issue with radeon driver on Ubuntu 16.04

i recently upgraded my sytem to Ubuntu 16.04. Since there is no fglrx driver for my AMD gpus, i had to use the radeon driver.


My OpenGL application runs two windows on two gpus (each within its own thread). I used GLFW library. The gpus are two Radeon HD 7870.


The application crashes when the second window tries to swap buffers. If I comment out the second swapbuffers call, everything runs at least.


I tried with a much simpler test program, having two windows on the same gpu, with the same results.


I know the driver development for Ubuntu 16.04 is still in progress, but maybe someone has an advice or workaround for this issue.


Thanks in advance.
