OBS Capture with osu! - Laggy window capture during gameplay + encoding issues caused with Automatic capture method

[Adrriii]

When using osu! fullscreen mode during gameplay, the KPS counter becomes very laggy, even if it's entirely visible on a second monitor. This is not related to OBS since the software itself is visibly lagging.

However, on top of things, when using Window capture mode with the Automatic setting, the KPS software causes huge encoding errors for the whole recording. (it is fine when specifying the Windows 10 capture method). This tells me that there could be serious performance issues related to the software when some application is running in fullscreen, if attaching a capture to it causes such instability to OBS.

It is also important to note that the KPS software caused multiple OBS crashes during streaming and/or recording when causing encoding errors.

This was recorded on the latest versions of osu!, OBS (31.0.0) and this software (8.9)

Hi, thanks for the extremely detailed report! I can't reproduce this (at least not with OBS 27.1.3, might try updating later), but probably the most important factor here is the Java distribution you're running. I'm not seeing any issues with Eclipse Temurin Java 17 so that might be worth a try, especially if you're still on an older Oracle release of Java 8.
