1658189 - Slow, visual resizing effects when moving between 100% and 150% scaled Wayland display

Status: RESOLVED WORKSFORME

(Core :: Graphics, defect, P3)

Description

[Jan Vlug]

I have a Fedora Wayland GNOME session with two displays. A regular, 100% scaled one, and a HiDPI, 150% scaled one.

When I drag a not maximized Firefox window, that is small enough to fit completely in each of the displays, between de displays, I see rather ugly and slow visual effects when the Firefox content is scaling to the scaling factor of the display it is moved to.

Hi Martin. I do not have the monitors any more where I saw this issue. Anyway, I tried to reproduce it with my current setup in the scaling that I described initially. Everything is fast now. So, I suggest that you close this issue with the correct resolve state, as I do not know what to select.

As a side note: I do see a little bit of flickering when moving the Firefox window between the differently scaled displays, but that is another issue that does not bother me.
