[W10] Artifacts left behind when the Download manager's width is resized
[Affected versions]: - latest Nightly 57.0a1 - Beta 56.0b9 - RC 55.0.3 [Affected platforms]: - Windows 10 x64 [Steps to reproduce]: 1. Launch Firefox. 2. Open Firefox's downloads manager. (Ctrl + J) 3. Change the width size of the download manager window. [Expected result]: - No artifacts are displayed while resizing the Download manager's width [Actual result]: - Artifacts are displayed while resizing the Download manager's width [Regression range]: - Last good revision: d29f84406483c721a13cf9a52936ecced0c5c98a First bad revision: c54c652af04c5a918610bc3d419250177a68b9f7 Pushlog: https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=d29f84406483c721a13cf9a52936ecced0c5c98a&tochange=c54c652af04c5a918610bc3d419250177a68b9f7 [Additional notes]: - I was able to repro this on a a HiDPI monitor (Dell UHD-1 P2415Qb) and with different scaling levels e.g. 125%, 200%. It appears that this issue is still present if I Sign out and Sign in back in Windows 10. On Win 8.1 and Win 7 I'm not seeing this artifacts. - on a low dpi monitor I cannot see this behavior

Has Regression Range: --- → yes
Has STR: --- → yes
This looks like graphics bug to me, but I can't reproduce it on latest Nightly (Win10) on a Dell XPS 13. If we could narrow down further the regression range it would definitely help.
Component: Downloads Panel → Graphics
Product: Firefox → Core
Jeff, invalidation problem?
Priority: -- → P2
Too late for a fix in 57 since we are a few days away from release.
Looks like this is on the graphics team's backlog at this point. Dropping this from regression triage.
