1204523 - [e10s][TSF][TS_E_NOLAYOUT] The suggest window position of Japanese MS-IME for Win8.1 and Win10 is sometimes positioned top-left of the screen

Status: RESOLVED FIXED

(Core :: Widget: Win32, defect)

Description

In e10s mode, the suggest window of Japanese MS-IME for Win8.1 and Win10 are sometimes positioned at top-left of the screen.

According to the log, the cause might be that we return TS_E_NOLAYOUT at unexpected time, but I still doesn't find the reason yet.

I don't see this issue in non-e10s mode, but if you see it, let me know.

Attachment: part.2 Hack TSFTextStore::GetTextExt() for TS_E_NOLAYOUT issue of MS-IME for Japanese

This is exactly same hack as for Google Japanese Input.

You know, we are going to remove the hack for Google Japanese Input, we should duplicate the code rather than merge with them. Because if we need to uplift some patches around here for other urgent bugs which would be found in the future, this is easier to merge the patch.

Did you report the bug to Microsoft?

Not yet. I'm still looking for a good email address. (I need to report the bug of Chinese TIP's too)

Hmm, even with these patches, I rarely see this bug. (one per hour?)

But the frequency is too low, so, I've still caught the log at failure. Anyway, we should fix it in another bug.
