Is this an issue in my code or in my Linux distro? (lemmy.world)

Display of OpenGL context works fine on Windows, no issues with resizing. Function glViewport works as intended.

It only has issues with X11 on Linux (no plans yet to implement Wayland due to lack of free time). Resizing breaks everything, and it doesn't really work the way you expect (point of triangle moves down if you make it taller, etc). I cannot find anything on if I should call anything else besides glViewport, only that "you should use [insert already existing library], which will take care of this behavior". Others are suggesting me that it's an issue with my distro, but I cannot find any OpenGL testcase that is small enough to test on my VM or my Raspberry Pi to actually test whether that's the case.

ResizeRedirectFlag

Did you mean ResizeRedirectMask?

Xlib docs for that say:

Similarly, a single client can select for ResizeRedirectMask on a parent window. Then, any attempt to resize the window by another client is suppressed, and the client receives a ResizeRequest event.

which definitely sounds like it could cause misbehavior.

Glad to hear you've made progress, and good luck on the rest of your project!
