Title:
  In mixed monitor(4K+1080p) config window switch monitor gives wrong
  position

Status in xorg package in Ubuntu:
  New

Bug description:
  It started in Ubuntu 25.04. In Ubuntu 24.10 it worked as expected. To
  reproduce a problem open app like Mozilla Firefox, press Super + Shift
  + -> (right arrow key). Window switches to another monitor but has
  wrong size. It happens in Microsoft Edge(flatpak) as well. I have
  Wayland enabled in Edge options, coz if it uses X.org mode it's even
  worse(wrong window size, position, DPI after move to second monitor).

  What's strange is when I move Firefox to second monitor, it has wrong
  (1/4 of screen?) size, but when I click another window, like terminal
  app, Firefox size suddenly becomes correct (why???). Then it's kinda
  fine, but I need it to resize correctly when moving to another
  monitor, like it did in Ubuntu 24.10. I think it's not graphics
  driver, but some bug in Gnome or Wayland or Ubuntu-specific
  modifications, but maybe I'm wrong.

  I believe it's a bug, and want it to be fixed in future updates. Thank
  You!

  My monitor configuration:
  first main monitor (4K) - on left - connected to Display port
  second monitor (1080p) - on right - connected to HDMI(same videocard)
  AMD Radeon RX5700 with open source driver (default one from Ubuntu, I didn't install any drivers)
  when I turn on PC, my BIOS logo is shown on 4K monitor. I use Windows 11 in dual boot and it has no such problem, so it's not hardware.
