To Reproduce

Steps to reproduce the behavior:

1. Enable plugin simple-tile
   I haven’t found that configuration options matter/change a thing, but just in case, i have the mostly-default configuration of :

[simple-tile]
animation_duration = 200ms circle
key_focus_above = <super> KEY_R
key_focus_below = <super> KEY_U
key_focus_left = <super> KEY_F
key_focus_right = <super> KEY_J
key_toggle = <super> KEY_G
preview_base_border = \#404080CC
preview_base_color = \#8080FF80
preview_border_width = 3

2. Resize a tiled window with simple-tile.button_resize
   Note it sometimes doesn’t happen.
   Additionally, oddly enough, from my testing it doesn’t seem to happen by spawning in new windows that are immediately tiled, i need to manually resize them for it to happen.

Describe the bug

Affected windows will be slightly blurry. Here, a screenshot of the wayfire wiki at roughly the same window dimensions, when not tiled and not blurry :

And, when affected by the issue :

Start by reproducing the issue with the simple-tile plugin and its simple-tile.button_resize action on the reported Wayfire version and hardware. Compare windows that were immediately tiled with windows manually resized after tiling, then trace the resize path to identify where the affected window becomes blurry. Done means manually resized tiled windows remain as sharp as equivalent untiled windows without changing normal tiling behavior.
