Hello @kassindornelles, this sounds like a hardware issue and not related to Proton. There's a suggestion that this related to the LEDs in the mouse. Try reducing the brightness of those LEDs in your mouse.
@kisak-valve already turned off my mouse LED's, it's funny because it only starts to get hot with Proton games, native one's the mouse remains cold :man_shrugging:
I'm closing the issue for now until i get some proof that proton/wine is the problem and not the hardware itself.
proton 5.0-3x1 2020-03
When i am playing native linux games my mouse is cold but when i start a Steam Play game like DOOM 2016 with proton 5.0-3 it starts to get hot, at some point i just have to stop playing the game to avoid damage.
It started recently.
I'm not sure of what is causing the issue.
also im using the mouse in a USB2.0 port, i'm not sure if it would happen on USB3.0.
I will comment on this bug report confirming if it happens with older versions of proton, it still requires testing so wait for updates.
