Just tried the full version in the upcoming v25 and:
- It installs and launches fine
- Fullscreen & pointer capture works (probably because of your workarounds) - although when getting out of fullscreen, sometimes only the game canvas/background get resized, not the controls on the left
- I'm seeing the same resizing issues
I'll look into all of these (not seeing them in desktop Chrome) - I think some of them might be due to what the itch app tries to do with canvas games by default (so they fit in the full window), I might have to adjust the heuristics
No ETA yet on v25, still got a bunch of testing to do!
