I know Gare usually launches an improved splash screen for each new release.
Well there probably isn't going to be new "release" following the next for Xara Designer Pro X 365 as it would be continual upgrades thereafter.

I believe the current splash screens are BMP files so no alpha channel for transparency.
I, however, propose two file formats for your splash screen submission: BMP and PNG.

Hopefully, Xara will see a ways to loading up PNG files with transparency so we can rock in our design; the BMP entry is the default fall-back.

Aim for 500 x 310 px (Golden Ratio).
Must include the Application Name, MAGIX and space for copyright texts (lorem ipsum will suffice).

Note: all past Pro splash screens seem to be angular, formal and rigid; XWD ones are more web screen centric.

No prizes, only the accolade of your peers. Only one entry each (1xPNG & 1xBMP or either).

Personally, if I could add animation, I would - a 365 day countdown timer for the 365 Day Update Guarantee.
You're on the clock.
