Windowed X11 application

SUMMARY

When using the option that allows X11 apps to apply scaling themselves, apps are still blurry unless they are maximized. 

STEPS TO REPRODUCE
1. Set a fractional scale in Wayland
2. Enable the option that lets X11 apps apply scaling themselves
3. Open a legacy app and observe the crispness when it is windowed and maximized.

OBSERVED RESULT

When using the option that allows X11 apps to apply scaling themselves, apps are still blurry unless they are maximized. Apps look more crisp when they are maximized.

EXPECTED RESULT

Legacy apps are crisp when windowed and maximized.

Possible the same issue as Bug 457143?

I don't think so. The person who created that bug is using 1X scale. I am using fractional scaling with the new option that doesn't scale xwayland apps.

I am closing this. It appears to be fixed by MR !2765.
