Reen Crashes My GPU - Linux - Possible workaround found in settings.

[MightBeFluffy]

Load up the save. Go talk to Reen after following the Teladi. GPU crash. Happens every time, but only in fullscreen. In windowed mode, I can talk to Reen just fine.

System:
Radeon RX 7700 XT
Linux 6.15 (also tried 6.14.7) w/ amdgpu
Mesa 25.0.5
Wayland 1.23.1
Sway 1.10.1
Gentoo

Google Drive folder with save and logs from the game and kernel

hey friend. please take a look at post viewtopic.php?t=402324. i will totally help you but if you would like more additional support, they will require more information.

so the game is modified, looks like most people wont touch it. could you start a unmodified game and try and talk to reen again? sadly it might be a mod that is causing this.

The information there is quite good for a Linux user although a VulkanInfo would be handy if made available. The past modified state of the save may be an issue and would have been worth mentioning in the OP.

[MightBeFluffy]

I do apologize for not noting a modified game and not putting VulkanInfo, I have updated the folder. The mod is question is NoMiningPenalty, a basic scripting mod. I will see if I can get the crash to happen in an unmodified game. The game has never crashed before or after this point and is running smoothly.

I hooked up Vulkan validation layers to the game and got no crash, but turn off the layer and it goes back to crashing every time. This might, unfortunately, be a case of the machine spirits being angry.

Edit:
Got the game to crash unmodified. Used the wayward scion start. I have updated the folder. The crash happens with Reen during "cinematic" dialog. Could not find any crash dumps

im currently using mesa 25.1.1. is there a chance that you could update your mesa? might just be a mesa/vulkan issue that was fixed.

[MightBeFluffy]

No luck with upgrading to mesa 25.1.1, still crashes. Reverted the game to 7.5 and no crash.

[xAix1999]

i'm guessing that the vulkan validation layers are able to correct your issue for obvious reasons. though im curios as to the performance impact, i would expect it to be low. if it's not noticeable then it seems you have already found the work around.

other than reproducing the issue in a virtual machine with a supported distro and submitting a new thread for support, i can trying and reproduce the issue but i also have an unsupported distro. i can start a new game and check it out though. let me know about your thoughts and interest in pursuing a fix.

as an afterthought, try x11(some other de) instead of wayland/sway. i know that shouldnt fix it since wayland it quite mature these days but maybe there is an edge case here not explored yet.

[MightBeFluffy]

Well I was able to work around it by just putting the game in window mode. As I noted in the OP, it only happens in full screen. I'm skeptical of it being a Xwayland issue or anything else in the stack. Using the same exact setup but running version 7.5, no crash happens. But, when I switch to 7.6, GPU crash every time I talk to Reen with cinematic dialog. One thing that stands out to me from the change notes for 7.6 is the change to "how the game handles GPU memory."

i did a few missions with your save and i was about to bomb the dock then got hugged by xenon while the coffee maker was announcing it's ready. your save started me at the beginning of reen's quest chain. i also had to edit the save to remove hyperion pack so maybe that reset the progress. is there another save in the g drive that i'm blind to find?

nevermind, i found it. i was not able to reproduce your crash.

[MightBeFluffy]

By random chance I not only learned that it was my setup but also what was causing it (sort of). Amdgpu dynamic clock speeds can be messy and Messa does not like that. By set pp_power_profile_mode to manual and pp_power_profile_mode to 3D Full Screen seems to fix it

Where do you set these parameters? I'm curious if these settings are what cause unexplained weirdness every so often on my laptop..

Given the information you provided, you might have a greater chance of resolution by opening a bug report against mesa3d: https://docs.mesa3d.org/bugs.html

It seems like a bug within the driver itself. So upgrading to the lastest version of mesa for your current branch might be best. For you that would be mesa 25.0.7. I'll highlight something relevant for that release:

Bug fixes :
...
RADV: Potential bug with vulkan fragment shader interpolation (on outputs from mesh shaders?)

Which seems to be related to your crash.
