0000616: Enter Fullscreen exclusive mode is lagging after window update
Windows 10 has installed its update yesterday, and i found that it took 5s or so to enter full screen exclusive mode, during which the video seemed to freeze while the audio is playbacked normally. In the OSD version toggled by ctrl+j the rendering and present time increased by 3-4 times in the first 5s when switching to the fullscreen exclusive mode. No such lagging is seen before the windows update is installed.

If i turn off "enable automatic fullscreen exclusive mode" in general settings, windowed mode is used in fullscreen and no more lagging, with rendering/present time increased by 2 times.

I've tried on mpc-hc/mpc-be with different video source (avc/hevc/8bit/10bit/FHD/HD/SD), the lagging is always happening when fse mode is entered.
1. check 'automatic fullscreen exclusive mode' in madvr general settings.
2. open source file, and enter fullscreen mode so fse is automatically on.
3. image is freezing for about 5s, but audio is normally playbacked.
4. everything goes fine after 5s, and some frames are dropped to sync.
Since this case is happened after windows update, and no more changes has been made, it is likely that the system is to blame for the lagging. I've found some issues that seems to be related, but no clear way other than turning off fullscreen exclusive mode can be found. If i turned off fse mode, the rendering time increasing (performance downgrade) would prevent me from playing quite a lot files with madvr.

Issues seem to be related: [^] [^]

madvr debug log is also appened, within which only open file-enter fse mode-recover after 5s is done.
No tags attached.
