--- Comment #27 from Alexander Glüsing <[email protected]> --- One more Info. I am running Manjaro Linux, and i used the Firefox version out of the Repositorys. (I don't know how to see if it is native or not) I think it was a Version, that did not have enabled Wayland Support (as a native Wayland client), So i installed the fedora-firefox-wayland-bin package from the AUR. The firefox version which is patched to be a native Wayland client has not the problem. I could use all Functions and use all links and it show the correct behavior all over the whole Screen. While at the same time The standard repo Version of Thunderbird has the Issue. (I guess it is a not native wayland client - through xwayland) Maybe it is importand that for me it seems to be every time the same region which behaves false. it is always the top left quarter of the 4k screen which is good, the rest quarters are "bad". that screen that i every now and then change the scaling. but it does not matter if i scale it down to 1080p and back or down to 1440p and back to native (100%) - The affectet region stays the same while it is at 100%scale. - while i have it scales to 1440p there ist no "bad regeion" - while i have it scales to 1080p there ist no "bad regeion" There is another indication what might get wrong: - if i use the scale factor 1.01 (kscreen-doctor output.2.mode.0 output.2.scale.1.01) basically only 1% more pixels rendered and scaled to native Resolution then there is no "bad" regeion - if i use the scale factor 0.99 i again get the buggy region on the screen. but also with some luck? sometimes the bug disappersa. lets sy i change the scaling factor from 1.01 to 0.99 the bad region disappers in 0.99 factor. But i can trigger it immediately by scaling to factor 1.5 and back to 0.99 - then i have it again at 0.99 : it seems to be that only scaling factor's of 1 and lower (0.99↓) are affected? but to trigger it i need to scale somewhere above the factor 1.0 like 1.5 once and back to 1 or lower I used thunderbird to look for the bug by searching of the animation for links (the links schould get lines under them) just as indicator. -- You are receiving this mail because: You are watching all bug changes.
