Hello @GamePlayer-8. Thanks for reporting this and helping to make Electron better!

Would it be possible for you to make a standalone testcase with only the code necessary to reproduce the issue? For example, Electron Fiddle is a great tool for making small test cases and makes it easy to publish your test case to a gist that Electron maintainers can use.

Stand-alone test cases make fixing issues go more smoothly: it ensure everyone's looking at the same issue, it removes all unnecessary variables from the equation, and it can also provide the basis for automated regression tests.

Now adding the blocked/need-repro Needs a test case to reproduce the bug label for this reason. After you make a test case, please link to it in a followup comment. This issue will be closed in 10 days if the above is not addressed.

1. Download the latest Virt image at Alpine Linux download page.
2. Launch it in qemu with:

qemu-img create -f qcow2 alpine.img 30G
qemu-system-x86_64 -cdrom alpinelinux.iso -hda alpine.img --enable-kvm -smp 4 -m 4096

3. Install alpine through setup-alpine command (after logging in a password less root user).
4. After installation boot up the installed system and run the snippet:

#!/bin/sh

echo 'https://dl-cdn.alpinelinux.org/alpine/edge/testing' > /etc/apk/repositories
echo 'https://dl-cdn.alpinelinux.org/alpine/v3.20/main' >> /etc/apk/repositories
echo 'https://dl-cdn.alpinelinux.org/alpine/v3.20/community' >> /etc/apk/repositories

apk update
apk upgrade
apk add shadow alpine-conf sudo
useradd electron
echo "electron:electron" | chpasswd
usermod -aG video electron
usermod -aG audio electron
usermod -aG tty electron
groupadd privileged
usermod -aG privileged electron
echo '%privileged ALL=(ALL:ALL) ALL' >> /etc/sudoers
mkdir /home/electron
chown -R electron:electron /home/electron

setup-wayland-base
setup-xorg-base
apk add linux-headers
apk add code-oss plasma sddm elogind plasma-wayland-protocols

echo 'ELECTRON_OZONE_PLATFORM_HINT="wayland"' >> /etc/environment

rc-update add sddm default
rc-update add elogind default
rc-service elogind restart
rc-service sddm restart

5. Login to SDDM as electron with password electron and select Plasma Wayland session.
6. Go to Display Configuration setting in the bottom left menu.
7. Set Scale below 100% (i.e. 60%) -> Apply.
8. Again from the application menu launch code-oss and try upscaling it.

hope this helps
