I understand your frustration but basically logs show that you are getting random GPU lockups, searching Google for "radeon r7 370 lockup" shows a lot of results even from Windows. So at this point I believe this might be a hardware problem.
I considered a hardware problem, but that seems unlikely for many reasons: The video card is still very new (about an year now) and a solid Gigabyte model... I've had another Radeon / Gigabyte card before it, which lasted me for nearly a decade. This issue is also triggered only by the KDE desktop, when certain desktop effects play or I select some windows (even with effects turned off)... I play high-end games on my machine, yet even they don't trigger this exact crash! The behavior of the crash also closely indicates a software problem... hardware issues usually cause a total freeze (Kernel panic), whereas this only freezes the desktop (without mouse pointer) then causes the monitor to shut down.
I can't see if in this bug report but did you try to set kwin to use XRender instead of OpenGL? -- You are receiving this mail because: You are on the CC list for the bug.
