--- Comment #2 from Stefan Hoffmeister <stefan.hoffmeis...@econos.de> --- Looking at the code at https://invent.kde.org/plasma/kwin/-/blob/3cc8e9f13bd011670c3a763bdaf3a508b5270a1d/src/backends/drm/drm_connector.cpp#L267 I am not sure how missing EDID data could result in this functional problem? Resizing seems to leave the number of modes unchanged, but changes the content of the _preferred_ mode, so the modes probably are detected as `!equal`, so the mode list gets updated. I do not see why that new / updated preferred mode (at the same position as before) does not get activated. Is there special casing required for "virtual" connectors? Or is "mode has not changed" detection too aggressive? Unfortunately, there is no additional debug logging in that area. -- You are receiving this mail because: You are watching all bug changes.
