Unlikely to be blink paint related since this is in browser UI. Possibly https://chromium.googlesource.com/chromium/src/+/b1068403be34a565e8be1aafe2fc7a2f0ba3f3eb?

@bruthig, I'm not very familiar with the browser UI code. If this isn't your patch, could you help triage this?

Suspecting https://codereview.chromium.org/1896363004 from changelog.

@erg: Please help in re-assigning if it is not related to your change.

Attaching chrome://gpu information.

Able to reproduce this on Linux Ubuntu 14.04, chrome version:52.0.2717.0, with the attached gpu.

**Worked fine on the same chrome version with 'NVIDIA/Quadro 600/PCle/SSE2' driver on Ubuntu 14.04.

[reland] x11: Don't wait on a MapNotify on override-redirect windows.

[This reland should theoretically fix a case where timing issues on
AMD drivers appear to cause a blank window by forcing a redraw when
we are an override-redirect window and receive a MapNotify.]

Some window managers do not send MapNotify on override-redirect
windows. Enlightenment doesn't send one, XFCE does, and I don't know
which behaviour is more common.

This makes mapping resilient against whether we would have received a
MapNotify message on override-redirect window. On override-redirect
windows, we immediately trigger the code that would run in the future
MapNotify handler, and ignore it in the future MapNotify message if it
is already run.

Reason for revert:
Forcing a draw didn't actually fix the blank submenu issue.

Revert seems to have worked and Issue is working fine on the latest M-52(52.0.2725.0) on Linux Ubuntu 14.04 on the system with the gpu as attached in C#2.

[Auto-generated comment by a script] We noticed that this issue is targeted for M-52; it appears the fix may have landed after branch point, meaning a merge might be required. Please confirm if a merge is required here - if so add Merge-Request-52 label, otherwise remove Merge-TBD label. Thanks.

[Bulk edit]

Our blockerbot script was offline; it was recently brought back online, and thus labeled many old issues (including this one) erroneously.  Removing Merge-TBD label since all milestones for this issue are already completed; no further work should be done.
