TSAGE: BF: Graphics weirdness and overwriting in map

Reported by: tsoliman Owned by: dreammaster
Priority: normal Component: Engine: TsAGE

I am getting a weird graphics overwrite the very first time I use the map when you scroll right and left. I cannot properly screenshot it. Here's a save just before it.

I can replicate this with Linux x86_32 on current Git master: b89bc000d96fce9d4e977b8ad59391282e35704e

Attaching a screenshot of my observed graphics glitch which is a large black vertical block when scrolling horizontally... Looks like an issue with calculation of scroll redraw width. This is a regression as this didn't happen with my previous playthrough. No associated valgrind issues. Will attempt to bisect.

TSAGE: Implemented dirty rect handling in the engine

This should help improve performance when scalers are being used.

dreammaster: Can you take a look at this?

comment:4 by digitall, 12 years ago

dreammaster: N.B. The clipping of part of the "pop-up" HUD/inventory in the map screen when scrolling left and right (normally part of the right side of this) was present prior to the dirty rects change and isn't related... Not sure if this was present in the original...

I've just done some commits which fixes the dirty rect handling, with the result that you'll no longer get those black areas on wide screens.

As for the inventory area, it's not meant to show the inventory area on the map screen. Since you say it was present prior to the commit for dirty rect handling, could you provide the steps you go through to make it appear? When I try going to the map screen the inventory area is correctly hidden.

Can't replicate this anymore... Probably fixed by dirty rects reversion (and I was wrong).
