More information is needed. What is your monitor setup, display driver, LLVM/Mesa version (if applicable), etc.
Monitor: W541 laptop display ( 15.6 in, 1920x1080 )
Display driver: i915 ( I guess)
Also
$ rpm -q llvm Mesa
llvm-6.0.1-1.1.x86_64
Mesa-18.1.5-204.2.x86_64
Fallout Shelter was on the Whitelist. Why is this labeled as "Unofficial?"
Thanks @RiderExMachina, label adjusted.
Having this issue as well. The only thing rombert and I share is the i915 driver. Otherwise running Mesa 18.3dev and llvm7 on Debian Sid.
Manjaro(Archlinux) XFCE

AMD FX-6100
AMD Radeon HD 7800 Series
relosution 1360x768 (monitor 18.5)
mesa 18.1.7
llvm 6.0.1
Game runs perfectly so this really maybe an intel bug related.
Nothing extracted yet.
Using Steam on openSUSE Tumbleweed, Kernel 4.18, Intel GPU (i7-4810MQ).
