--- Comment #15 from vyproyects@gmail.com --- Hi
I have done some more checks although I haven't finished all of them due to lack of time. I'm writing them now to give you some early feedback, but I'll keep checking though.
I double checked the commit and regression testing was right. The regression SHA1 is still 70d842b106d3ccbb0a786a41474903bddc4ea879.
I also checked on another computer with an Intel HD Graphics card that also runs i915 driver. As you say everything works as expected even with my own copy of the game not only with the provided one.
Besides I couldn't reproduce this other bug https://bugs.winehq.org/show_bug.cgi?id=48385 either, which was found on the same computer. Therefore we can confirm both bugs are related.
My suspicion is that some dependencies might be bad configured or even be missing on my computer. As a result I tried to completely remove wine and reinstall it, but this didn't solved the problem.
On one hand I think I didn't uninstalled it correctly as the system had never asked me to uninstall all dependencies, but just wine package. So I'll keep trying.
On the other hand as an answer of your question I have two GPUs: intel is an integrated graphics card and amd radeon is a dedicated graphics card.
Therefore intel's should be disabled as long as amd radeon is the main main graphic card in use. That's the way Windows works and all other Linux distros I've worked before.
Today I have checked again lspci -v | less command and I have realized that Display controller section says Kernel driver in use: radeon and Kernel modules: radeon, amdgpu. What I interpret of this is there are 2 available drivers installed on my computer: radeon and amdgpu; but driver in use is radeon.
I've also checked with Synaptics and as I suspected all three drivers are installed: i915, radeon and amdgpu, as well as some other drivers like ati I do not use. Ubuntu might install all of them during installation.
My next check is to try unistalling radeon driver and try to use dedicated graphic card with amdgpu driver or intel's otherwise.
I'll also check what happens if I change resolution as you ask.
