Borderless Fullscreen support

[Axer128]

Currently the only fullscreen option triggers exclusive fullscreen. Exclusive mode is not desirable on modern systems, though doesn't hurt to support both.

Hello! Thank you for the suggestion.

I have updated the fullscreen picker to offer a borderless windowed option. Please give it a try and let me know if it works for you! https://github.com/mstan/MegaManX6Recomp/releases/tag/v0.0.7-alpha

Going to go ahead and close this issue since I haven't gotten any feedback on it. If the borderless doesn't work how you'd like, feel free to respond here or open a new issue.

Take care!

Tested latest version (v1.0.3) , no change: Both exclusive and borderless modes result in exclusive mode on my system. (lengthy black screen flicker on alt tab while either mode engaged)

Can achieve proper borderless mode via magpie (avail free here on github) by setting game to window mode first and using magpie to scale to borderless.

But yea native feature not yet working.

Also both fullscreen modes should hide the windows mouse cursor since its not used. Atm they do not.

Relevant system specs:
Win 11 25H2
i7 14700KF
RTX 4070Ti , latest drivers
1440p, 360hz monitor. windows DPI scaling set to 125%

Thanks for following up. I think I may have figured out what happened here. I think this got implemented, and then silently regressed when I moved MMX6 from SDL2 to SDL3.

Would you mind to download this pre-release and give it a try for me?

Choose Borderless, try alt tabbing out and back a few times. Let mek now if the flash still occurs. Also let me know about the cursor (should be hidden now).

I've attached a COLLECT_FULLSCREEN_DIAGNOSTICS.bat you can run while it's running if you're still seeing issues. Hoping that'll get me the info I need. Output should be fullscreen-diagnostic-*.json . you can also run it in Exclusive too and give me that output too. But only do so if you're finding issues are persisting.
