Comment # 15 on bug 1090456 from Mauro Gaspari

I made some progress. Tested a bit more on Arch and Ubuntu, and same issue
happens there as well. Kernel 4.18.x combined to mesa above 18.0.5 causes the
problem, on all distros i tested. As I am more familiar with Ubuntu, I
Installed 18.10, kernel 4.18.0-10 I tried up to Mesa 18.2.2 available on
various Xorg repos for ubuntu. Same issue perists.
Next step I enabled oibaf repositories that hold latest mesa from git.
https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers
Followed instructions, upgraded system and rebooted. Mesa was updated to
18.3.0-devel, and the issue was resolved. 
I did not have much time to play but I left a Wine-based game running overnight
and there was no crash, no hang, no freeze.

Is there any way to enable extra development repos on tumbleweed so I can test
Mesa 18.3.x as well and compare results?

Thanks
Mauro
