3. TextMeshPro abuse with WOTC DisplayName = 100% win rate against Desktop and iPad opponents

   MTG Arena does not sanitize user Display Names. A nefarious user can create a Display Name with TextMeshPro markup to have an unfair advantage (100% win rate) against players using Desktop and iPads. This can cause frustration with other gamers and lead to loss of revenue if paying customers decide to leave the platform.

   However, in performing this abuse, a player has lost a lot of game functionality themselves. For example, they must also play on mobile only or play with a modified client on an affected device.

   It is easy for any user to create a new account (no email verification before you can play), a very easy exploit for users to abuse.

   Due to the reasons listed above, I’d classify this as a low (maybe medium) risk/issue.

   Proof of Concept / Reproduction steps:

   Register a new WOTC account at: https://myaccounts.wizards.com/register

   Create a character Display Name with TextMeshPro size markup and >= 4 unicode block elements:
   <size=9999>████

   [photo 1 - displayname]

   Upon playing, you will notice match screens will show a large white box (the name).

   Example photo, me playing a game against Sparky:

   [photo 2 - affected game]

   I have also confirmed a real opponent sees the same thing on Desktop when battling this user.

   I did not test on an iPad myself, however, I believe they are affected as online videos of iPad use (example link: https://www.youtube.com/watch?v=ZewSXhYKRB8) show names displayed on screen, unlike mobile phones which are not affected (tested on Android).

   [photo 3 - iPad client YouTube video]

   Mobile devices are unaffected as Display Names are not shown at all times during the match. The user abusing this will have to use a mobile device (or an otherwise patched client) to get past the tutorial and play human opponents.

   Remediation:

   Sanitize user input before passing to [TextMeshPro] sinks and/or restrict WOTC display name character sets.

4. MTGA macOS fullscreen resolution bug reintroduced (Aug 20, 2025 patch)

   Platform: macOS (MacBook Air M2 13", 2560×1664 display, Epic Games Launcher)

   Since the August 20, 2025 patch, MTGA no longer respects custom fullscreen resolutions on macOS.
   Before this update, I was able to run the game in 2560×1440 fullscreen (16:9) using Epic Launcher arguments (-screen-fullscreen 1 -screen-width 2560 -screen-height 1440).
   After the patch, MTGA forces fullscreen into native 16:10 (2560×1664), cropping UI on the left/right edges, and ignores any -screen-width/-screen-height overrides.
   Windowed mode still works correctly and allows 16:9 resolutions, but fullscreen no longer behaves as expected.

   Steps to reproduce:

   On macOS, set Epic Games Launcher additional arguments:
   -screen-fullscreen 1 -screen-width 2560 -screen-height 1440

   Launch MTGA in fullscreen.
   Observe that the game ignores the requested resolution and forces native 16:10 with cropped UI.

   Expected behavior:
   Fullscreen should respect the requested 2560×1440 (16:9) resolution as it did prior to the Aug 20, 2025 patch.

   Additional notes:
   This bug was first reported after the v2025.48 update in April 2025, and seems to have resurfaced in the Aug 20, 2025 patch.
   Multiple users have confirmed the same regression on macOS.
   Windowed mode works as a workaround, but fullscreen is broken.

14. When resolution is 3440x1440, game automatically resizes to 2560x1440 when entering and leaving match

    Here's the specific log:

    [185939] Current screen dimensions of 3440x1440 are not an allowable ratio (2.388889) so we are forcing windowed mode.

    I see threads about this issue so I'm just another drop in the bucket but I mean come on... the game looks great with 4k and it plays fine during matches and on the menus, however I'm guessing there's one specific scene during the match transition that doesn't allow that ratio so this is what we get...

16. Error Updating Data PC and Mobile

    After the new update for MKM Alchemy on both my PC and mobile app I get the "Error Updating Data" message when trying to launch Arena. I have uninstalled and reinstalled multiple times (PC and mobile) including manually deleting the files on PC, switched between wifi and cell data and tried multiple different connections (mobile), run corrupt file search/cleanup (PC), and tried installing through Epic Games Launcher (PC) and I have had no luck. MTGA Status page says everything is fine, but I don't know that there is anything else I can do on my end to fix the issue.

    Update - My girlfriends mobile app was working for her account and successfully completed the recent update. Since I knew her update had worked with no corrupt files, I logged her out and tried to log in and was met with the same error message, so it has to somehow be linked to my account.
