MCL-10940Launcher does not scale properly on Linux, affecting HiDPI displays
When using the Minecraft launcher on Linux, the launcher does not scale its content according to the system's display scaling factor. According to user reports, this affects multiple Linux distributions, desktop environments, and windowing systems.
Impact
Users with HiDPI displays have extreme difficulty viewing and navigating the Minecraft launcher. Since the launcher does not scale properly according to the display scaling factor, the size of content is very small. For example, text with a 12px font size would be 4px on a typical 4k 13.3" laptop with 300% scaling (equivalent size as 150% scaling on a 1080p 13.3" display).
How to reproduce
- Set a display scaling factor on your Linux distribution that is not 100%. For example, on Linux distributions with the GNOME desktop environment, go to Settings > Displays > Scale and set it to 200%.
- Open the Minecraft Launcher.

The scale of the launcher content does not match that of the system. On HiDPI displays, the text size is unreadable and the interface is difficult to navigate.
Notes
If I remember correctly, this is an upstream issue with CEF. However, I can't seem to find a relevant issue report.This does appear to be an upstream issue. When using the latest beta build of the CEF sample application (94.2.2+g0c2cc26+chromium-94.0.4606.50), the scaling of the content is not correct on a HiDPI display.- In launcher versions prior to 2.2.2159, the content was scaled correctly. However, the resolution of the window was not changed, causing it to appear blurry. See
MCL-16405. - Since launcher version 2.2.2159, the size and resolution of the window are set properly, but the content scale is not. Try running the launcher with GDK_SCALE=1, GDK_SCALE=2, and GDK_SCALE=3. Notice how the window size grows, but the content size does not.

Affects launcher version 2.2.5516 (beta, released 19 September 2021). This version does not yet exist in the Affects Version/s category, so this comment is temporary until this issue can be updated properly.

Currently working on this, Arisa seems to have matched some of your environment information by mistake (regex was incorrect). Sorry for the inconvenience. As you might have noticed, the devs have already relinked your ticket to another ticket about the same issue, MCL-10940. Feel free to leave a vote or any additional information on that ticket.
When using the Minecraft Launcher on Linux with a HiDPI display, the resolution of the window is set incorrectly, causing it to appear blurry to the user compared to other nearby UI components such as the window title bar.
While the scaling of the window is handled correctly at 2×, the resolution is never changed to reflect this. For example, on a LoDPI display with scaling at 1×, the window is rendered at 1000×600 and displays in a 1000×600 pixel area. Each pixel rendered is displayed as one pixel on the screen. When this is taken to a HiDPI display with double the pixels on the screen, the window is correctly scaled by 2× to achieve the same physical size as the LoDPI display. The issue here arises when 2× scaling causes the window to render at 1000×600 in a 2000×1200 area, causing each pixel to display as 4 physical pixels. After this, the pixels are interpolated, causing them to appear blurry.
This is not a duplicate of MCL-10940, as MCL-10940 pertains to the scaling of the Minecraft Launcher, not the resolution of it. In my use case, MCL-10940 seems to have been fixed, as the window scales correctly at 2× the size. This issue may have been caused by the attempted fix for MCL-10940.
I have attached a screenshot of the issue using Minecraft Launcher version 2.2.909. Notice how the title bar is much more crisp and sharp to the eye than the rest of the Minecraft Launcher when zoomed in.
With launcher version 2.2.2159, it appears that this has been resolved, however MCL-10940 does occur again. This issue may be marked as resolved.
Closing as a duplicate of MCL-10940, as it seems to describe this issue. Thanks!
We updated the CEF libraries in the current version. Does it help with this in any way?
I can reproduce the issue in 2.1.5411.
Issue still occurs. Uploaded new screenshot
Happens for me too, attached screenshot.
The latest version now scales correctly for me!

Same here, KDE X11 with 150% scaling on arch linux.
It doesnt scale properly
Starting from launcher version 2.2.2159, I am experiencing this issue again. I think this issue affects all Linux versions of the launcher, not just the Debian one, since I have experienced it on other Linux distributions. If it is helpful, I am using X11 and Mutter. I have attached a screenshot of the issue on version 2.2.2159.
I have just updated to the last launcher version, and now I wish I hadn't..
I now also have this issue.
Kubuntu 20.04
The launcher version I used was pretty recent, maybe the version before.
I'm running launcher 2.2.3200 and I have the same issue.
Ubuntu 20.04 LTS -> Monitor: 4K(3840x2160) with 175% of scale DPi.
Se more details on screenshots attached.
Gave ownership to Bytzo, as they have been the one updating it through Discord requests recently.
Updated the issue summary, as the issue affects more than just the launcher Debian package. Also updated the issue description with more details.
This is most likely an issue with CEF. In the latest beta build of the CEF sample application (which you can download from https://cef-builds.spotifycdn.com/index.html), the scaling is not correct on a HiDPI display.
Passing the --force-device-scale-factor argument should allow for the scaling to be manually overridden in CEF applications. This works with the CEF sample application and is used in the Spotify Flatpak to support HiDPI displays.
However, this does not appear to work with the Minecraft Launcher. Running minecraft-launcher --force-device-scale-factor=2 has no effect on the scaling of the application. This still does not work when executing the CEF binary directly (located at .minecraft/launcher/minecraft-launcher) with the argument.
Because of this, I don't think there are any current workarounds for this issue. If possible, having the ability to set the --force-device-scale-factor argument could be a temporary workaround until a proper fix exists upstream.

Commenting to mention that this is still an issue in the newest version of the launcher (2.2.11697) and Linux Mint (20.3), and that the CEF --force-device-scale-factor workaround still does not work either.
Still an issue on 2.3.280 with Pop!_OS 22.04.
Still an issue on 2.3.462-1.1.32 on Pop!_OS 22.04
Had this issue on Ubuntu 22.04 on version 2.3.549
Linux Mint 21.1 Cinnamon and the issue persists, the text is literally unreadable and it looks like there's nothing to do except pray that someone will fix this
This issue might be fixed with the latest versions of CEF. According to this commit which removes HiDPI-enabling code in CEF for Windows, Chromium was changed to support HiDPI by default. When testing the latest cefsimple sample application on Fedora Workstation 39, everything seems to be scaled properly. So, sometime in between whatever version I tested 2 years ago and the latest version of CEF, HiDPI support on Linux was fixed. The fixed version of CEF might be around or before April 2023 based on the time the commit linked above was made: I am unsure of the exact version this was fixed since building one version of CEF takes several hours on my machine making a bisect impractical.
To make text slightly more readable, in the launcher go to Settings > Launcher Accessibility Settings > Make Text Bigger

This seems like a CEF issue and should be reported at https://github.com/chromiumembedded/cef/issues
As of version 2.29.15, the launcher seems to be scaling correctly when using Fedora Workstation 40 at 200% scaling. Is anyone else able to confirm that this is issue fixed?
The issue is no longer happening with version 2.29.15-1.12.5 on Linux Mint 21.3 Cinnamon at 125% or 200%.
