Spoke too soon again. Restarting the computer left me with a black screen on the next boot up. I could run krunner and yast but could not see the desktop or the panel. My GPU is the SAPPHIRE Vapor-X 100364VXL Radeon R9 270X 2GB 256-Bit GDDR5 PCI Express 3.0 CrossFireX Support OC WITH BOOST Video Card It's a pretty high end card, and I just built this machine early this summer, so heat should not be an issue. It is now running at a steady 35℃ for the GPU. I have read a lot of announcements that indicate TW is best supported by the free drivers, so I don't think using fglrx would improve the situation, in fact I suspect it will make it worse. Oh well, this is what living on the edge feels like! It's what I signed up for when I thought stable releases were getting boring. :-) For now I have disabled the compositor on startup, and will now install some debug symbols for the next batch of tests.

What graphic card do you have? For me this issue sounds like a step back for your video-driver due to the newer kernel version. This does happen sometimes. Your GPU might overheat. Above 90°C most computers shut down for safety reasons.
Start KSysGuard (you are using KDE, right - if not something similar on your DE) and have a look at the HW-temperatures. If it's not working, install "sensors" from the package "sensors". Just call "sensors" in the terminal to see what temperatures your CPU and GPU is working or even better run a shell-script and log it.
In case, consider switching to the proprietary video-driver (does it work with TW???) or do some research whether a kernel upgrade or downgrade might improve your situation.
Maybe this is a hint that can help you. Simon

Online, it would be Flash sites like Crunchyroll. Offline, it is with mpv using either smplayer or bomi as the GUI frontend, playing mp4, wmv, and the usual formats.
I have toggled various settings in the KDE compositor since writing the last email, and the latest one with the Scale method set to Crisp, rendering with OpenGL 3.1 with EGL as the interface, and suspending compositor for full screen windows has been the most reliable set-up so far. Managed to make it through a whole episode in Crunchyroll without crashing.
