This is an important point. There are many solutions out there (beyond compositing) that add incredible complexity along with other costs in order to solve a perceived problem by it's proponents... not uncommonly those same people pushing the solution are incapable of fairly judging the cost benefit - sometimes the solutions are just not worth the cost.
There is currently an issue in chromium compositing with checkerboarding (blanking whole regions of the screen with white) when scrolling due to an optimization released to reduce jank:
https://bugs.chromium.org/p/chromium/issues/detail?id=1062662 https://bugs.chromium.org/p/chromium/issues/detail?id=106266...
You will notice this in recent releases of chromium when you scroll any non trivial page fast enough... or a simple page very fast by yanking the scroll bar... unless you have an extremely fast computer and graphics card. When reading through that thread you will notice how defensive they are, it's a complex and no doubt incredible bit of coding they have done - unfortunately the side-effect is worse than the original problem that most users don't even notice.
In the long run I think time will prove this problem and it's solutions are purely transient... In the same way font anti-aliasing is becoming obsolete with DPIs higher than we can perceive, solving jank isn't necessary if you cannot perceive it (i.e using frame rates > 60 Hz)... and the original problem really isn't as bad as all the people attempting to solve it think it is anyway.

Even on a 400ppi phone screen at typical viewing distances it is possible to tell whether a slanted line is anti-aliased or not. Font anti-aliasing is not becoming obsolete any time soon.
- pekim 6y agoI agree, anti-aliasing is certainly still required at 400dpi. Although subpixel anti-aliasing is not.
