the issue is about the graphic stack hanging waiting for a reply message (xcb_wait_for_reply). As a result the front panel UI (based on Qt5) freezes.
At this stage we cannot pinpoint the root cause, we tried to analyse buffers, kernel logs, DRI, libdrm but could not find anything obvious. The GPU seems to be working fine after the issue occurs. We also tried to upgrade parts of the graphics stack from Mesalib-9.1.3 to MesaLib-10.4.4.tar.bz2, libdrm-2.4.40 to libdrm-2.4.58, xf86-video-intel-2.9.902 to xf86-video-intel-2.99.917 and the issue still occurs.
