Poor fullscreen support with widescreen monitors and tiling window managers

spectrwm-2.7.2-x86_64-1_SBo

When enabling full screen support, it defaults to 1280 x 1024 8bpp even if I select 1680 x 1050 24bpp, but this is not the main problem.

The main issue is that when using a tiling wm (Spectrwm) jfsw fails to fill in the screen and will display anything in the background while displaying a strobe effect. Here is a scrot somewhat showing what I mean.

In spectrwm I can have focused tiled windows overlap floating windows with a feature called 'always_raise', if this is turned on the sides are properly displayed as black, but the spectrwm bar is still visible and the strobe effect resumes if the bar is hidden...

This doesn't occur for me anymore, I guess it must of been fixed or worked around elsewhere. I will close this until it can be reproduced again.
