I'm trying to run the game on Linux Mint 20 (Ubuntu 20.04), and I'm getting:

X Error of failed request: BadDrawable (invalid Pixmap or Window parameter)
Major opcode of failed request: 149 ()
Minor opcode of failed request: 4
Resource id in failed request: 0x4600013
Serial number of failed request: 275
Current serial number in output stream: 281

Other Unity-based games seem to run just fine, so no, it's not a problem with my setup. I'm on the 440.100 stable branch of the Nvidia driver.

Is anyone else seeing this?

Thank you :). I did not even dare to hope you guys were monitoring the GOG forums. Was mostly waiting for feedback from other goggers.

I figured out what the problem was, and maybe it is something you can potentially address, since I'm not seeing this in any of the other Unity games I have lying around. It's sort of a corner case though.

I was playing around with GPU video encoding these days and wanted to give Intel Quick Sync a try, so I had enabled my iGPU.

Turning it back off gets the game to start correctly. I guess it was trying to use the iGPU instead of my 1080, but since my monitor's connected directly to the 1080, X sorta had a seizure.

Maybe the problem is with intel cpu video? i face the same issue and only with this game. I have a nvidia integrated card that im not using so im using only the intel card in the cpu

Do you have Vulkan installed? I ask because I had the same problem and that fixed it.

The game uses Vulkan only.
I've tried with "-force-glcore45" and previous versions (from 3.2 to 4.5), but with no success.

I have the same problem on
Manjaro Linux
Cinnamon 4.8.6
Kernel 5.10.42
Radeon HD 7790

./start.sh: Zeile 16: 19863 Abgebrochen (Speicherabzug geschrieben) ./"Hellpoint.x86_64"

(Vulkan is installed)

Edit: I solved it myself. My system was running on the older radeon kernel driver instead of amdgpu. The easiest way to switch was to edit /etc/default/grub inserting/editing following line: "radeon.cik_support=0 amdgpu.cik_support=1" and updating grub.
