[GL 2.0 / GL 3.2 Core] Linux: Game runs on wrong screen when disabling windowed mode

[mrmatteastwood]

Steps to Reproduce:

1. Compile bstone for Linux on a multi-screen PC
2. Launch bstone executable
3. In main menu, go to Game Options > Video > Mode
4. Select Renderer GL 2.0 or GL 3.2 Core
5. Disable option "Is Windowed"
6. Confirm

Expected Result:
The game should switch to full screen and stay on the current monitor.

Current Result:
Game jumps to different monitor.

Notes:

• Trying to move the window to another screen using Super+Shift+Arrow Keys moves a static snapshot of the window to the other screen. One can still move around the UI, but the image no longer changes.
• Issue only occurs with the two renderers listed in step 4 above.
• Video showing the issue: https://youtu.be/1Wd7iBmW6PM
• I compiled bstone in an Xubuntu VM, then moved the resulting install folder to my host machine (Linux Mint 20.2).
• My system specs: https://termbin.com/t2eyy

What about the latest development version?
There is no exclusive fullscreen mode beginning with v1.2.12 (at least from a92fe65).

Afraid I can't check, since the latest dev build won't launch:

./bstone
BStone v1.2.12

Looking for game content.
Found "Blake Stone: Aliens Of Gold" v3.0.

fwiw, I saved the output of the whole compiling process this time. Since I'm a noob at compiling, perhpas I'm doing something wrong there. » https://pastebin.com/uHzvveWi

Notes: btw, bstone runs flawlessly on Linux using Wine. Also, thanks for this awesome source port. :-)
