From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

More details on your GPU and how you installed your drivers would be helpful to understand your issue. You should not need to explicitly enable GPU permissions in every flatpak as some of these comments are suggesting. That is to give apps direct GPU access, which is not necessary for hardware acceleration. A lot of the info in this thread is not accurate.
just kidding :3
external monitor or internal?
both
I had a laptop where the HDMI/dvi slots ran off the CPU instead of the GPU. Maybe worth to investigate?
