[Bug 2156709] Re: Xubuntu 26.04 flickers on ThinkPad X1 Carbon Gen 14

Is `xe.enable_panel_replay=0` enough by itself? ** Tags added: psr ** Changed in: linux (Ubuntu) Status: Incomplete => New ** Summary changed: - Xubuntu 26.04 flickers on ThinkPad X1 Carbon Gen 14 + OLED flickers on ThinkPad X1 Carbon Gen 14 -- You received this bug notification because you are subscribed to linux in Ubuntu.

The flickers are random, and they seem to occur more often when the pointer moves over the edges of windows. The flickers become even more observable in google-chrome, where they occur (randomly) when the pointer moves over links. Thank you for taking a look.
