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.

    Full repository: https://github.com/ZILtoid1991/iota

    Testcase for OpenGL: https://github.com/ZILtoid1991/iota/blob/main/gltest/app.d

    Code that creates the window: https://github.com/ZILtoid1991/iota/blob/main/source/iota/window/oswindow.d

    Note that I also get an X connection to :0.0 broken (explicit kill or server shutdown). error message every time I close one of my x11 testcases, and I find nothing about this error message (besides the usual "use preexiting library" suggestion).
