SUMMARY
I have 3 monitors set up (see https://ibb.co/G9P8WQh). I am maximing an glfw
application and on the right most monitor is one pixel par on the side still
free. Interstingly it stays white when the cursor moves (see the attache
screenshot).
STEPS TO REPRODUCE
1. Grab 3 monitors and an nvidia gpu
2. Open minosoft https://gitlab.bixilon.de/bixilon/minosoft, go into rendering
and then maximize the window
OBSERVED RESULT
See the one pixel wide border on the right between both monitors.
EXPECTED RESULT
No border
