1589611 - [Wayland][Basic] Stuck render state after maximizing or restoring window with non-default theme

Status: RESOLVED WORKSFORME

(Core :: Widget: Gtk, defect)

Description

[Kestrel]

Attachment: Redraw stuck after restoring window

STR:

1. Start with MOZ_ENABLE_WAYLAND=true and default Basic compositor on Ubuntu 19.04.
2. Enable dark theme.
3. Maximize then restore window.

The window appears unresponsive (no hover state, location bar does not update) and the web content doesn't shrink to fit window. Resizing window corrects it.

Does not happen with WebRender or OpenGL compositors.

Before the regression there were sometimes transparent areas after maximize/restore but otherwise the window was redrawn without getting stuck.

Regressed by Bug 1574036.

Confirming the same misbehavior when running using the swaywm, last commit tested 4b332005f92551e4c96e74a150a601764f76aa02

One note different from the original report: here it's also happening with WebRender Compositing.

Resizing the window and then restarting firefox makes it stuck in the size after resizing, but not when maximized or fullscreen.

Martin is this something you want to try to fix for 71?
