--- Comment #8 from Francisco González <fgonzalez.n...@gmail.com> --- Some observations: - About the screen mode changes on TTY switch, the screen frequency regression to 60 Hz is noticeable but is not informed by KScreen, which shows 75 Hz. - Even though I'm not an expert on this, it seems that the lack of DRM_CLIENT_CAP_ATOMIC support on my graphics card and some problem with KWin handling that, might be the cause of the screen corruption. - In the duplicated bug referenced before, the user has a Radeon HD 6310, which seems to be pre-GCN (one gen before my GPU). That could mean that this bug might be replicable with HD 7000 series GPUs or older. - Running drm_info on my laptop (Intel UHD Graphics 620) shows support for DRM_CLIENT_CAP_ATOMIC, and there are no artifacts at all. PS: somehow, got baited into this 2016 article that might be related to this issue.
