Firefox window mess after notebook sleep

[Kolouš]

When I close my laptop (Dell 7559) and then start again from sleep Firefox content is only in 1/4 of the window and the rest is filled with mess. I have every time to press the unmaximize and maximize button to have content in the whole window. See attached screenshot.

I think this is related to graphics setup not to Firefox itself. The laptop has 4K display which is tragic to use in Ubuntu with scaling. Therefore I use HD resolution and 100% scale which works much better. This behaviour is observed when using both Inter or Nvidia (with nvidia drivers) graphic.

There are multiple other issues related to this setup. Before unmax/max the cursor size jums to 4x when hovering over top bar or left side bar. And Liferea layout is messy after new start before clicking on a channel.
