    Hi Andrei

    I also had troubles with the fglrx driver. But not only with Bricscad. The fglrx driver seems buggy, especially with the Evergreen series (HD5xxx).
    I solved this by changing the parameter GLSWAPMODE ( Settings -> Settings ... -> Program Options -> Display -> GL Swap Mode ). I set it to "Call glCopyPixels to copy back to front, do not call glXSwapBuffers".

    I still have a little flickering with the selection rectangle, but nothing very serious.

    I hope it will also solve your problem.

    Mandriva 2011, AMD 64bit, fglrx driver, ATI Radion HD 4200 Graphics Chip.

    Using glswapmode = 3 here.

    Any attempt to use a value of 4 causes a hang.
