Thanks for trying to reproduce, and yes, the issue is still reproducible 100%
despite chromium browser and kernel update in the meantime (although it seems
to be able to recover more often until a freezes completely) - but trying to
watch a youtube-video with hw-acceleration enabled in chrome settings will
trigger rsc hang / will be completely unusable. Same for the particles demo -
fine with hw-accel disabled, and triggers the issue with hw-accel enabled.

Very likely you get rsc hang just for restarting chrome after enabling
hw-acceleration.
Here's chrome://gpu on my system with hw-accel enabled:

Canvas: Hardware accelerated
Flash: Hardware accelerated
Flash Stage3D: Hardware accelerated
Flash Stage3D Baseline profile: Hardware accelerated
Compositing: Hardware accelerated
Multiple Raster Threads: Enabled
Native GpuMemoryBuffers: Software only. Hardware acceleration disabled
Out-of-process Rasterization: Disabled
Hardware Protected Video Decode: Unavailable
Rasterization: Software only. Hardware acceleration disabled
Skia Deferred Display List: Disabled
Skia Renderer: Disabled
Surface Synchronization: Enabled
Video Decode: Unavailable
Viz Service Display Compositor: Enabled
WebGL: Hardware accelerated
WebGL2: Hardware accelerated

differences to your output is that "Hardware Protected Video Decode" is listed
as unavaliable on my system, and "Rasterization" is software only, "Video
decode" also is unavailable here.

Thanks for offering to test with same distro as I have - Magiea released a
beta1 of the testing version recently, and has live iso (and classical
installers) available from https://www.mageia.org/en/downloads/prerelease/ that
you can dd to a usb-thumbdrive
