v0.19584 has the same behaviour in fullscreen mode, even though the game starts windowed.

this is most likely a support case.

Please delete your
windowPositionAndSizeConfig.tag
in the starmade directory while the game is not running.

It should fix the positions on next start then.

That stopped it from briefly displaying the StarMade window at 1280x720 on boot, but it did not fix the mouse issue.

"Game doesn't work" sounds more like a game breaking bug than a support issue to me.

Upload your settings.cfg (located in ./Starmade), do the same for logstarmade.0.log (./Starmade/logs) and graphcisinfo.txt (./Starmade/logs)
Drag and drop the files in the comment section to upload them, don't paste their content in here.

I assume the native resolution your laptop is set to is 1920 x 1080 and not 1280 x 720?

3840x2160

If I delete settings.cfg, the game loads at 1380x768.
I click Options->Graphics and set Resolution to 1920x1080, check Fullscreen, and click apply, and then OK. It changes the resolution to 1920x1080, but the mouse is stuck in the 1380x768 range, and I can't click on anything. I hit Alt-F4 to get out, rather than waiting for the count down.

I load the game again, it briefly displays the screen at 1380x768 (I'm guessing), before displaying the fullscreen 1920x1080. The mouse is still stuck. Attached is the files resulting from that process.

uh .. this is old :/

so you are running the game at an 4K screen and scale it to that screen by setting it to HD ?
just for a test could you try to set the game to 4 K and see if the mouse then operates correctly ?
the settings do show 1920x1080 at fullscreen being selected and the logfile claims to have found that capability on the display device.
And it is also using the laptops proper GPU .
looks all good so far in these log and setting files.

4K (3820x2180) works correctly, although the UI is unusably small.

Setting it to HD? I don't follow.
In Windows 10 display settings, the setting "Change the size of text, apps,
and other items: 150% (Recommended)".

For starmade-launcher.exe, in the compatibility tab, setting "Disable
display scaling on high DPI settings" makes Starmade behave correctly at
1980x1024. Which implies that SetProcessDpiAwareness() (in shcore.dll) is
being called.

Ah, yeah, well the windows built in scaling options do not play well with most games.

They cause many side effects, and would need windows specific code, as they seem to handle it without telling the application about the difference properly.
While UI scaling is a planned feature for the future.

That "Compatibility Mode" alleviates the issue proves that this is not a fault with Windows, rather that Starmade (or one of it's libraries) is telling Windows that it understands and will handle DPI itself, and then failing to handle it correctly.

"Compatibility Mode" tells Windows to ignore all calls to SetProcessDpiAwareness(), and forces GetDpiForMonitor() to always return 96 (a scaling value of 1.0). So yes, this is actually a fault on the application side. Be it a 3rd party library you're using, or a piece of code somewhere.

Yeah, exactly its the LWJGL causing it, that part is out of our code range to my knowledge.
So we can look into it again after updating our LWJGL.
