Using a solid color as a background color doesn't work

[MinekPo1]

Describe the bug Using a solid color as a background doesn't work, to me it looks like the background is not cleared between framed.

To Reproduce Steps to reproduce the behavior:

1. Open app with default settings (or non default settings which uses a solid background color)
2. See error

Expected behavior The background uses the color set in the settings. Note the flickering ghost images visible when pannig/rotating the camera.

this issue does not apply if a gradient background is selected

interesting, cant reproduce on the provided continuous appimage (I experienced this issue when building from source), I'll see if building an app image makes the issue not apply

edit: cant, my system is "too new" :P

[MinekPo1]

I can reproduce this issue when building v23.03, this may be an issue with my system maybe?

use the gradient option and put the same color on both, see what gives - possibly related to another bug

the bug does not apply in that case
