Fix resize artifacts (stretching, bumps)

[vaxerski]

WIP

Fixes resize artifacts notably when using the mouse to resize apps to larger sizes (stretching etc)

ref #7475

[vaxerski]

ready for review

[diniamo]

Um, I don't see a difference.

[vaxerski]

well I surely do, mind to get a recording?

[MahouShoujoMivutilde]

Definitely can see the improvement.

And with patch

patch-foot-no-anim.mp4

Notice no bg flash on the left window.

[diniamo]

Oh, that's the only thing I wasn't looking at. A lot of the other problems are still there though.

[vaxerski]

this frame is odd, as the patch should expand the texture along the edges. What's that terminal and what settings?

[MahouShoujoMivutilde]

It's because its 1.25 monitor scale, can't reproduce on 1

Foot on defaults (with my bindings and colors), and hyprland now with hdefault-min.conf.txt

This patch does this to my wallpaper at 1.25 scaling:

Other than that and not fixing Electron resizing artifacts it does seem to fix stretching etc overall when resizing other things.

[vaxerski]

looks very nice.

[vaxerski]

can't repro, what wallpaper daemon?

[ferrreo]

can't repro, what wallpaper daemon?

hyprpaper,

For more useful repro steps, it's a 4k wallpaper at 3440x1440 resolution @165hz for monitor config with 1.25 fractional scaling.

[Agent00Ming]

Used it for a while, can't really tell the difference tbh. No noticeable problems have come up either.

Can also see this effect #7499 (comment) with nested sway and cage

With patch

Without

Latest git aqua / hl

[vaxerski]

I should revisit this mr some day

[diniamo]

some day

😭

[vaxerski]

some fixes including for those stretched things, but if I launch two terminals quickly they kinda wonkily stretch still

lmk if there are any other issues.

I am also doubting a bit whether this is the best solution. I mean, what should we fill the gaps with?

[vaxerski]

any1?

[PaideiaDilemma]

I think even with animations this is a clear improvement.
Here is how it looks on my config.
OLD:

hyprland_old_stretchy_resize.mp4

NEW:

hyprland_new_resize.mp4

Did not find any issues with it so far.

[MahouShoujoMivutilde]

Nested sway/cage issue is fixed.

This #7499 (comment) still happens

Details

scale 1.25, slowed down

scale 1, normal speed

[vaxerski]

it's still better than main no? Lmk if there are any important bugs. The quick open bug is one that is annoying to me but I can live with it.

Basically, open two kitty terminals in quick succession, the first one will kinda squeeze, which looks odd.

@MahouShoujoMivutilde I am unsure why your one happens

[MahouShoujoMivutilde]

It's definitely better. I don't see any other bugs, nor do I see any problem with kitty.

clearly visible here

[MahouShoujoMivutilde]

Oh, yeah, I see now. I just had my

    bezier = cst, 0.84, 0.37, 0.2, 0.62
    animation = windows, 1, 7, cst
    animation = windowsMove, 1, 2, default
    animation = windowsOut, 1, 3, default, popin 80%

so it wasn't visible to me.

With animation = windows, 1, 7, cst, if I open another terminal during about midpoint of the opening animation of the first, this I can reproduce the similar effect, but in the form of a vertical stretching, for both kitty and foot.

magic

[MahouShoujoMivutilde]

Most likely, xwayland crashed for me for the same reason #7936 happens.

Idk what triggered it first two times, but it's unrelated to the patch.
