Can we get some confirmation this is really a fractional scaling issue? On the affected machine, please run:
gsettings get org.gnome.mutter experimental-features > experiments.txt xrandr --verbose > xrandr.txt and then attach the resulting text files here, as well as a copy of: ~/.config/monitors.xml ** Changed in: mutter (Ubuntu) Status: Triaged => Incomplete ** Tags removed: xrandr-scaling -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1868207 Title: Fractional scaling window sizes incorrect after resume from suspend Status in Mutter: New Status in mutter package in Ubuntu: Incomplete Bug description: LP bug as requested at https://gitlab.gnome.org/GNOME/mutter/issues/1122 From the summary there: With fractional scaling enabled, after resume from suspend, maximised & half tiled windows have been resized/scaled so they are too large for the screen, and as a result no longer fit on the screen. Not sure if it also happens to windows that aren't in either of these states, I rarely have any. Further, most but not all windows are scaled like this. Epiphany and Terminal definitely are, maybe XWindows clients like Emacs aren't? Under 3.34, shell/mutter seemed to notice this and would visibly snap the window sizes back to what they should be. Under 3.36, that no longer seems to happen - the windows stay too big and I need to manually fix them.
