![]() This is what originally happened to Chromium: it simply drew itself at 100%, and that image was then stretched by the system compositor. So, if some application has no idea about the system scale and renders itself normally, the compositor will upscale it. The system scale there is respected by the compositor when pasting buffers rendered by clients. However, Wayland does it a bit differently. If it does not, it will look perfectly sharp, but its details will be perhaps too small for the naked eye. It is the application that is responsible to handle the scale properly. Despite having the system-wide scale, the system talks to the application in pixels, not in DIP. ![]() Note that for X11 the ‘natural’ scale is still the physical pixels. However, this is the very flag which did not work in the bug mentioned in the beginning of this story. The system scale is used as default device scale factor, and the user can override it using the command line flag named -force-device-scale-factor. The device scale factor can take fractional values like 1.5, but, because it is applied at the stage of rendering, the result looks nice. It works within this scaled coordinate system, known as device independent pixels, or DIP. This factor is applied equally to all sizes, locations, and when rendering images and fonts. Chromium does exactly that: inside it has a so-called device scale factor. Those which prefer doing everything themselves have to get the current scale from the environment and adjust rendering. For applications that use those standard controls, this is a happy end: everything will be scaled automatically. This allows all standard controls and window decorations to be sized proportionally. Modern desktop environments usually allow configuring the scale of the display at global system level. Since I finished this work, I have been asked a few times about what happens there, so I thought that writing it all down in a post would be useful. On my way to the solution, I have found that scaling support in Wayland is non-trivial and sometimes confusing. It turned out that support for HiDPI screens was entirely missing in our implementation of the Wayland client. Setting the buffer scale did the right thing indeed, but it was absolutely not enough. Like many stories that begin this way, this turned out to be wrong. Wayland allows setting scale for the back buffers, likely you’ll have to add a single call somewhere in the window initialisation’, a colleague said. Apparently it’s upscaled from low resolution. On the other hand, HiDPI on Windows was tricky even in 2014. This Chromium issue, dated 2012, says that the Linux port lacks support for HiDPI while the Mac version has it already. Ultra HD had been standardised in 2012, defining the minimum resolution and aspect ratio for what today is known informally as 4K-and 4K screens for laptops have pixels that are small enough to call it HiDPI. ![]() It is hard to tell now what was the first HiDPI screen, but I assume that their wide recognition came around 2010 with Apple’s Retina displays. A screenshot was attached where it was clearly seen that Chromium (version 72 at that time, 2019 spring) did not respect the screen density and looked blurry on a HiDPI screen. ![]() The description sounded humble and harmless: the browser ignored some command line flag on Wayland. new post-credits scene of showing how Peter Parker has been erased from history in a new edition of "Betty's Corner with Betty Brant" begins playing that recaps their high school years with all the footage and pictures missing Peter.It all started with this bug.an additional scene with Murdock and Hogan.a scene featuring May, Parker, and the villains in an elevator while on the way to Hogan's apartment.additional scenes in the basement of the New York Sanctum.Daily Bugle reports of Parker's first day back at school and the arrivals of Dillon and Marko.additional scenes of Parker at school Brant interviewing Parker, his teachers, and his classmates.the scene with Holland's brother Harry as a thief that was cut from the original release.additional scenes of Parker and May being interrogated by the Department of Damage Control.an introduction by Holland, Maguire, and Garfield.This alternative version had some additional, extended scenes and a new post-credits scene (replace the teaser trailer of Doctor Strange in the Multiverse of Madness (2022)) which weren't seen in the theatrical version of the film, taking the total runtime to 157 minutes. An alternate version of the film (titled 'The More Fun Stuff Version') was announced by Sony Pictures in June 2022 and was later released in September 2nd of that year.
