#796 SMPlayer does not enlarge particular videos in fullscreen mode to fit the screen

[Self-Perfection]

I have a bunch of mkv videos from one source (encoder) which are not enlarged to fit the screen in fullscreen mode of SMPlayer. Additional observations:

• All other videos are properly enlarged in fullscreen mode
• Faulty videos actually become a bit smaller than 100% size in fullscreen mode (not an optical illusion, have checked with a ruler)
• If played via bare mpv or mplayer (i.e. without SMPlayer wrapper), these videos properly fit the screen if fullscreen mode. The bug is within SMPlayer.
• I've observed this issue during most of 16.x versions, but after upgrade to 16.11.0 the bug dissappeared. Only to come back again after upgrade to SMPlayer 17.1.0 :(

Apparently there is something common in these videos that causes SMPlayer to misbehave. What Can I do to help fix the issue?

Here is an example video fragment (7MiB, 22s) that is not properly scaled in fullscreen mode

Part of smplayer logs which appears on enabling fullscreen:

Just in case, I use SMPlayer on Arch linux with KDE.

Is it displayed correctly if you turn off the option "add black borders on fullscreen" in preferences -> general -> video?

Yes, it is!
Thank you for the pointer, this is acceptable workaround for me.

This situation still looks like a bug for me though.
