Ok, so this bug can probably be reassigned to the specific wayland pieces, doing so. > If you still need me to test with different desktop environments: which o ne > would you suggest?

I just tried it with logging in to my account using Wayland or X. The blurry issue does not happen with X, only with Wayland. If you still need me to test with different desktop environments: which one would you suggest? I'd prefer one that is easy to install AND remove after the test.

GNOME in Wayland mode is nothing to do with Weston, apart from using the same protocol, so if there are bugs in its window compositing they'd be to do with either gnome-shell or libmutter-5-0. If those windows look blurry, one possible reason would be that the compositor is somehow drawing them at a position that is not correctly aligned to the pixel grid, or placing the external screen at a position that is not correctly aligned. The mentions of sleep mode and an external screen make me wonder whether this is to do with the external screen being re-detected after waking up. smcv

Oh, that's very odd. Are you running X or wayland? Better reassign to either xorg-server or weston. Perhaps also try different desktop environments to determine in which cases that happens. Samuel
Bug#947955: general: Windows on second (external) screen are blurry after notebook sleep
Package: general Severity: normal I have an external screen connected to my notebook computer (Dell XPS 13). After waking the notebook from sleep mode, the windows that have been opened before activating sleep mode are blurry. Newly opened windows are not affected. The issue happens with windows from all programs, not just a specific program. Moving or resizing the windows does not change the blurry appearance. I have reproduced the issue on a different notebook computer (HP hardware) with a different external screen.
