Paint.net on Linux Mint

Description: I finally figured out how to properly install Paint.net on my Linux disto {Mint} using POL [PlayOnLinux]
After some trial&error i got the whole thing to work just fine.
What you'll need:
PaintDotNetPortable_3.5.6.0_English.paf
dotNetFx40_Full_x86_x64 or follow the * to install it via POL Components Tested Wine Version: 2.21(Staging)

Here are the steps:

Step 1:
Create your virtual driver & configure it
Install -> Install a nonlisted program -> Install a program in new virtual drive -> Give it a name - > Select Configure Wine -> Select WindowsXP -> Apply & Okay -> 32bits windows installation Select Browse and select the dotNetFx40_Full_x86_x64.exe program.

* or you can close it and install dotNet40 through POL ->Configure -> Install Components ->dotNet40 but before installing it make sure you run this on your terminal first

echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope

Step 2:
After that either select the PaintDotNetPortable_3.5.6.0_English.paf.exe file and install it. When it will ask you where to install the programs just navigate through program files and install it where you have all your other vds'.
Step 3:
Select the PaintDotNet so it will create the icon and thats it.
Everytime it opens the tools are a bit bugged so you can press two times the F5 , F6 , F7 , F8 and they will load-up normally.
Step 4:
After that , enjoy.

UPDATE:
To install version 3.5.11 follow the below instructions:

2) Install playon linux. (get it from your distro's s/w repository)
3) Run Playon Linux and create a 32-bit XP or Windows10 virtual drive.
4) Use Playon Linux to install “dotnet40” (DotNet 4.0) on that virtual drive.
5) Use Playon Linux to install “gdiplus” on that virtual drive.  
6) Use Playon Linux to install PDN 3.5.11 (It's the latest PDN version I can get running) on that virtual drive.

Linux Stuttering Driver 380 VRAM BUG / Revert back to 375

Thanks a lot to the r/linux_gaming

So if you are experiencing stuttering in games (opengl/directx[wine]) and noticing a huge FPS drop every 6-7 seconds then this is caused probably because you are using an NVIDIA 38X_x driver which is reported to have a VRAM-BUG issue.

Link about the VRAM-BUG:
https://devtalk.nvidia.com/default/topic/1026874/linux/huge-performance-losses-with-newer-nvidia-drivers/post/5223375/#5223375

1) First of all open your terminal and check what is your gfx driver version:

inxi -F && dmesg | grep -i error

2) After that run also:

glxinfo | grep OpenGL

3) Open your Driver Manager and select nouveau as default driver:

4) Time to remove all nvidia drivers from our Unix System:

sudo apt-get purge nvidia*

sudo nvidia-settings --uninstall

5) Now lets install nouveau and reinstall some packages

sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core xserver-xorg-video-nouveau

6) Make sure that nouveau is not blacklisted:

cd /etc/modprobe.d/
ls

7) Reboot your system

8) Download the 375 driver (nvidia-375_375.39-0ubuntu5_amd64.deb)
http://us.archive.ubuntu.com/ubuntu/ubuntu/ubuntu/pool/restricted/n/nvidia-graphics-drivers-375/

9) Install the new driver , follow the steps for the MOK and SecureBoot(Disabled).

10) Thats it. Restart your system and try out the new driver.
11) Before launching a game check the driver version by running again

inxi -F && dmesg | grep -i error
