Ok thank you and sorry for the late reply I caught a cold over the last
days:
This is after installing the mutter builds:

Unfortunately Chrome,Firefox and other programs seem to run only
software accelerated and do not adjust their scaling for example if
moved from screen A (HiDPI) to screen B (low-DPI).
** Attachment added: "Here is the glxinfo.txt run during opened Chrome with one
Window on each screen opened, so one is correctly scaled (on HIDPI) and one
twice as large on screen 2"

Title:
Chrome and other programs not resizing on HiDPI and Non-Hidpi setup
Status in mutter package in Ubuntu:
Incomplete
Bug description:
To try the new support for EGLStreams and Wayland I have directly tried some
programs to see how this performs. Unfortunately there are multiple problems:
Chrome does not use GPU hardware acceleration anymore (I get huge CPU spikes
while scrolling on normal pages).
Also the automatic resizing when a program is moved from one display to
another only works with system applications such as settings, terminal etc. The
programs then are still scaled 2x on the Non-HIDPI screen.
I am running the latest NVIDIA Drivers with 418.56.
Is there a fix for this behaviour?
Best
Nicolas
