So I use a Macbook Pro Mid-2015 and I installed a flatpak. This led to many errors because of Vulkan support when my discrete GPU alr supports Vulkan. for ref:
MESA-INTEL: warning: Haswell Vulkan support is incomplete
MESA-INTEL: warning: Haswell Vulkan support is incomplete
How do I make it to use always the discrete one? I’ve also tried gpu-switch
Sorry, that we do have a private life …
This is a forum of volunteers and not a professional support center.
First of all it would be great if you could share your hardware info, as your macbook has a couple of optional configurations and we dont know what internals your really have, nor what drivers are installed.

Secondly, more info is always better, what flatpak application are you trying to run? What excacly did you do or try? Because this is fairly confusing, at least for me:
Third, patience.
Timezones, private live and people with jobs and so on exist. Also not everyone reading this (including me) are expierienced enough to maybe come up with a solution to help you, so we move on or, maybe give you a recomandation on what to do. Like me telling you to give more information to make people interrested and able to help.
Also, as marteng69 said above, this is not a professional support center noone gets paid for helping, we just help bc we like doing it, or because we have too much free time. 
If you are on plasma 6.5. go to system settings / application permissions / search for that flatpak you installed / click on it / click on “manage flatpak settings” in upper right corner / and scroll through that long list of settings including advanced. There might be a setting for what you are looking for. I only have an integrated gpu, so I can’t say for sure.
Sorry but I’m on hyprland. I’ll go to plasma though if it matters.
Here’s the specs:

Sorry for being impatient, I understand your concerns.
As far as I’m concerned there is no setting regarding this on my computer alteast.
I’m trying to run Lutris. I need Vulkan support to run most of the games I want to try.
Also error log 2 (using gpu-switch && flatpak run): MESA-INTEL: warning: Haswell Vulkan support is incomplete

yeah sorry.
i have no expierience neither with amd nor lutris.
maybe look at this and see if it helps, seems similar
