Comment # 21 on bug 1090456 from Mauro Gaspari

I have been doing a few more tests on other distributions to compare results
with kernels and mesa versions. I used KDE Plasma in all my tests: Kubuntu
18.04, Kubuntu 18.10, Arch, Arch testing.

Kubuntu 18.04. Kernel 4.15.x, mesa 18.0.5 - No issues. As I previously stated,
issues I reported in this bug, seem to start after the Ubuntu LTS kernels and
mesa come to play.

Kubuntu 18.10 Kernel 4.18.10 mesa 18.2.2 - Same issue as on tumbleweed.
Launcher does not render correctly. This is solved completely by adding the
oibaf repository and letting it upgrade mesa to git-master. After that change,
I have no crashes and launcher works fine.

Arch Kernel 4.18.16 mesa 18.2.3 - Launcher renders correctly, game starts, but
freezes randomly per original bug. However, interestingly, when the game
freezes, instead of locking the whole OS, now it only freezes the game process.
So i can kill it, and keep using my desktop. This is some nice progress.

Arch testing Kernel 4.19.0 mesa 18.2.3 - No issues with launcher, game starts
fine, and works without freezes.

I hope this helps.
