[Launchpad Bug Tracker <2115433@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

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.
