Thunderbird (and other gnome apps) show menus off the screen

bundabrg commented 3 years ago

Short Description

If I move thunderbird to one of the split screens then right click anywhere inside (or do anything that pops up a hover menu) the menu is shown on the wrong screen.

Details

In my case I have 6 screens in a 6x1 format in the following configuration:

A DP, HDMI and DP screens sitting next to each other, left to right. (Screens 1, 2, 3)
A DVI connected through a TripleHead2Go that connects to 3 more screens that sit to the right of the other three. (Screens 4, 5, 6 that are split using fakexrandr)

Putting Thunderbird on screen 4, 5 or 6 and right clicking inside will pop up the menu on screen 3 at the correct height.

Version

I'm running this fork of fakexrandr by @10110111 which works well under Kubuntu 21.04

Thoughts

I note that xrandr shows the virtual displays with a size of 0mm x 0mm. I have a suspicion that gnome apps (and potentially other ones?) may use this when deciding where to put floating windows. Since the screen has no size, it ends up on the screen to its left which has size.

I should add the three screens attached to the TH2Go are samsungs made in 2005 that have just lasted so well and still look so much better than my (slightly, 2009) newer ones. They don't make them like they used to.

Hello!

I've had this issue when using multiple virtual monitors, but this GDK patch here solved it: https://gitlab.gnome.org/GNOME/gtk/-/issues/2013#note_1026815

I will give it a shot, thanks. Does this mean the issue will have to be fixed in GDK and can't be done here? If so I'll try send an MR with that patch and see if it gets any further.
