I like what you did with house there.

Fixed controller input inconsistently working in Big Picture mode windows.

God yes.

Windows will absolutely wreck your Linux boot everytime it boots from my experience (I’m exaggerating the technical side a bit of course). The way I got my dual boot under control was to install easyUEFI on windows and from there to set Grub as Launcher: https://www.easyuefi.com/index-us.html Look here for a guide: https://superuser.com/questions/1247300/how-to-make-uefi-bios-start-grub-not-windows#1248255

Also later make sure windows has Fastboot and energy saving disabled or it will lock down your write access for any disk that is installed in your PC.

PDFs can contain a vast amount of different Image information, but often a good software that can edit vector data opens PDFs for editing easily. It might convert not embedded Fonts in paths and rasterize some transparency effects though. So Inkscape might work.
