<pre>If it may help to narrow the issue, I played with various fgfs startup options,
and noticed that _both_ multi samples option, and an odd window height value
(height & 1 == 1) must be selected to trigger this bug. An odd window width is
safe.
Changing the multi sample option causes a different visual to be selected, this
same visual (190) is used when 2 or 4 samples are requested:
glXChooseVisual(0x55d7155916a0, 0, {1, GLX_RGBA, GLX_DOUBLEBUFFER,
GLX_RED_SIZE, 8, GLX_GREEN_SIZE, 8, GLX_BLUE_SIZE, 8, GLX_DEPTH_SIZE, 24,
GLX_STENCIL_SIZE, 8, GLX_SAMPLES, 2, 0}) = &{visual = 0x55d71558fe78, visualid
= 190, screen = 0, depth = 24, c_class = 4, red_mask = 16711680, green_mask =
65280, blue_mask = 255, colormap_size = 256, bits_per_rgb = 8}
glXChooseVisual(0x559880b4ff20, 0, {1, GLX_RGBA, GLX_DOUBLEBUFFER,
GLX_RED_SIZE, 8, GLX_GREEN_SIZE, 8, GLX_BLUE_SIZE, 8, GLX_DEPTH_SIZE, 24,
GLX_STENCIL_SIZE, 8, 0}) = &{visual = 0x559880b49df8, visualid = 182, screen =
0, depth = 24, c_class = 4, red_mask = 16711680, green_mask = 65280, blue_mask
= 255, colormap_size = 256, bits_per_rgb = 8}</pre>
