Hi. Having same problem here regarding the yellow border.
It's started immediately after the update to OBS v27, which had an important display workflow change, according to the release notes:
"Added a new capture method for Display Capture, allowing the ability to capture displays cross-GPU. "
I use OBS to record and have just one source, which is my external monitor (Display Capture).
Up to OBS v26, I never had seen that annoying yellow border.
a) Can anyone confirm whether the "new capture method for Display Capture" may be causing the yellow border in systems like mine, which never had shown that border before?
b) I've seen several topics mentioning changing to "bitbit" capture for fixing the yellow border (which seems to appear in some systems even before v27 update). However, it is not clear in any topic I've read how to change to "bitbit" capture. Is it changed within OBS? Can someone please shed light on how to change a "Display Capture" source (external monitor) to "bitbit"?
Thank you!
